After c. 1,000,000,000,000 AD: "Hell Bent" establishes that the Doctor's home planet, Gallifrey, has been hiding at the end of time. (Note: dialogue in the episode suggests this point is only around 4,500,000,000 AD; however, this contradicts other episodes that place the end of time as happening much later.) Later in the episode, the Doctor and his companion, Clara Oswald, travel even further in time (see below).
100,000,000,000,000 AD: "Utopia": The last remnants of humanity (who have mostly evolved back into today's familiar form) seek out a legendary utopia in this year, aided by a Time Lord with suppressed memories, revealed to be the Master.

It is stated that Orson is on one of the last planets in the universe.
In "Hell Bent", the Doctor and Clara travel to a point when Gallifrey is orbiting the last star in the universe and is inhabited only by the immortal known as "Me".
Frank Herbert's Dune series spans thousands of years of distant future history in a galactic, and eventually multigalactic, setting, describing an interstellar feudal system enabled by a prescience-imbuing drug known as the spice.

25,065 AD: Events of Foundation's Edge. Golan Trevize attempts to locate the legendary Earth, only to discover Gaia, a previously unknown power in the galaxy, who offer an alternative to the Seldon Plan or a new Empire: Galaxia, a galaxy in which all life and nonlife is unified in a single intelligence.
25,066 AD: Events of Foundation and Earth. Golan Trevize locates Earth, now radioactive and uninhabitable, but ultimately locates Daneel Olivaw, a 20,000-year-old robot who has been secretly guiding humanity's evolution from a base on the Moon.
12,700,000-15,000,000 AD: Humanity has completely died out according to an alternate future described in The End of Eternity. This future was supposedly avoided by ensuring that humanity gained access to intergalactic travel. The book's connection to the Foundation series is contested, but several links have been established.
The Future is Wild
The Future is Wild was a speculative documentary hypothetising how life could evolve over the course of millions of years:
5,000,000: the world is in an ice age. The Mediterranean Sea will be a vast salt plain and the Amazon rainforest will be a grassland. Creatures of this land include huge killer birds, thin-legged pigs, sticky-frilled lizards and birds that act like whales. Humans, by this time, have either gone extinct or left the planet.
100,000,000: in 100,000,000 years' time, the world will be very hot due to excess volcanic activity. Antarctica will be a lush rainforest. Creatures of this world include dinosaur-sized tortoises, amphibious octopuses, four-winged birds and eusocial spiders. At this time, there is also only one species of mammal left, which is "farmed" by the spiders.
200,000,000: in 200 million years' time the world will contain one global ocean and one continent, like Pangaea. Approximately 100 million years before this time, there was a mass extinction and now most of the world's land is desert, with few rainforests. Creatures of this world include air-breathing flying fish, giant plankton, various huge worms, highly specialized insects and intelligent, arboreal land-squid. There are no mammals, no birds, no reptiles, no amphibians, only one species of flowering plant and only sharks left to represent aquatic fish. Other creatures have moved in to fill these niches.

"The Last Question"
Isaac Asimov's short story "The Last Question" charts the future evolution of Man as subsequent generations ask ever-more complex computers the same question: "Can entropy be reversed?" The story begins in 2061, when the supercomputer Multivac is asked the question and responds: "INSUFFICIENT DATA FOR MEANINGFUL ANSWER". The story then jumps forward to an unspecified time at least a thousand years later, in which a spaceship-borne computer is asked the same question, and gives the same answer.
ca. 22,000: Humans, now immortal, are filling up the Milky Way galaxy and are considering expanding beyond it. The Galactic AC is asked the question and replies: "THERE IS INSUFFICIENT DATA FOR A MEANINGFUL ANSWER"
ca. 10,000,000,000: Mankind now sleeps in hibernation as minds travel the universe. The hyperspatial computer the Universal AC is asked the question and replies, "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
ca. 100,000,000,000: Man, now a single cosmic intelligence, realizes that the stars are winding down. The Cosmic AC is asked the question and responds: "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
ca. 10,000,000,000,000: Man fuses with the AC and entropy destroys the universe. Some unspecified amount of time later, the AC, from its home in hyperspace, formulates its answer to the question and demonstrates it with the exclamation "Let there be light!"
10,000 AD: Post-apocalyptic future in which first the humans, then the apes, then the birds, then the cows, and then the ambiguous slug-like creatures each created and destroyed their respective civilizations.
50,000,000 AD: Advanced civilization composed primarily of scantily-clad buxom women.
1,000,000,000 AD: All life is extinct on Earth.
1040 AD: The universe ends. At some point later, a second universe begins.
10,000 AD, again: Post-apocalyptic future in which first the humans, then the apes, then the birds, then the cows, and then the ambiguous slug-like creatures each created and destroyed their respective civilizations.
1040 AD Again: The second universe ends. At some point later, a third universe begins.
3010 AD, after two complete cycles of the entire universe: The same exact universe, except ten feet lower.
The science fiction franchise Star Trek has made several allusions to far future events:
802,701: Most events in the novel occur in this year. The Time Traveller discovers a land in which the idyllic humanoid Eloi have been reduced to the level of cattle for the cannibalistic Morlocks, who reside underground and tend their "flock" above with vast machines
~30,000,000: The Time Traveller arrives at a twilit, desolate beach. The only inhabitants he sees are large, mothlike creatures and giant, threatening crabs.
c. Beyond 30,000,000: The beach is now flecked with ice and snow; the only observed life is a football-sized tentacled creature. In the more distant future, the Sun turns red and the planet is left Moonless. The Earth becomes a cold wasteland where all life (except for green slime) has died out.
14,000-25,000 AD: Dark Age of Technology. Mankind develops warp travel and reaches out to other star systems, in the process attaining its highest level of technical sophistication.
25,000-30,000 AD: Age of Strife. The rise of psykers and the influence of the Chaos Gods sends the human race into a period of anarchy. Persistent warp storms cut off many human worlds from the rest of the galaxy.
Early 30th millennium AD: The Fall of the Eldar occurs. the Chos God Slaanesh is born. The event calms the warp storms, allowing humanity to advance across the galaxy again.
30,000 AD: Age of the Imperium begins. Emperor of Mankind, after unifying shattered Terra, launches a Great Crusade to reclaim the human planets under his rule and locate the 20 Primarchs scattered across the galaxy by the forces of Chaos.
c. 30,004 AD: The Horus Heresy begins. The Emperor, after defeating Horus, is placed near death on the Golden Throne.
35,000: Age of Apostasy. The Imperium falls temporarily under the tyrannical rule of Goge Vandire.
c. 40,000–41,000 AD: Setting of the Warhammer 40,000 universe, it is the temporal setting for most of the related backstories, novels, video games and other spin-offs released as of January 2013.
41,999: The 13th Black Crusade's encroaches on Terra. Cadia is eventually destroyed by Abaddon.
41,000: The Ultramar Campaign and Terran Crusade see the Primarch Roboute Guilliman resurrected as he takes command of the Imperium. This action attracts the gaze of the Chaos Gods, and the Warp is thrown into a turmoil on a level unseen since the Age of Strife, creating the Great Rift, a galaxy-spanning gateway to the Warp.
7,000,000: in John W. Campbell's short story Twilight (1934), a man of the 4th millennium witnesses the decline of a dull human race, which has colonized the solar system and made machines supply all its needs.
ca. 8,000,000: In the works of Clark Ashton Smith, the time of Zothique, last continent of Earth, and home to the dying remnants of the human race. The culture is on a barbaric level, and magic has become dominant over science.
500,000,000,000,000,000,000: In Stephen Baxter's Manifold: Time novel, the last descendants of humanity, close to the Big Freeze, make some changes to our near present in order to release the universe's vacuum energy, spawn new universes, and prevent the Big Freeze from happening at this time.
14,292: On the distant finale of Aim for the Top! Gunbuster, mecha pilots Noriko Takaya and Kazumi Amano arrive on Earth 12,000 years ahead of their time, having entered on a Black Hole in the early 21th century and experienced the effects of extreme time dilation. The story of Diebuster, its sequel, takes place 10 years prior to EoG and ends with the same event, this time seen from Earth's perspective.
40,000: The film Barbarella takes place in this year.
ca. 50,000: In the Stargate Atlantis episode "The Last Man", by this time Lantea's sun has turned into a Red Giant, rendering the planet uninhabitable.

ca. 1,000,000: In the Babylon 5 episode "The Deconstruction of Falling Stars", approximately one million years after the founding of the Interstellar Alliance (2262 AD), humans evolve into beings of energy. They leave Earth for the old Vorlon homeworld—and ultimately destroy the solar system to keep any remaining technology out of the hands of younger races.
~3,002,100: most of the events of the sci-fi sitcom Red Dwarf occur around this time (the premise of the show is set "3,000,000 years into the future" after protagonist Dave Lister, who is from the 22nd century, is put into suspended animation for that many years).
100,000,000: The Cartoon Network series Time Squad takes place during this year where there are "no more wars, no more pollution, and bacon's good for your heart". Also, all the nations have formed into one supercontinent.
400,000,000,000: Ren & Stimpy's space adventures as Commander Hoek and Cadet Stimpy take place in this year.

^The disparity in the Xenogears years is due to the vagueness of the calendar conversions used in the game. The accompanying literature, Xenogears Perfect Works (PW), states that in AD 2510 the calendar system restarted and was labeled TC, for Transcend Christ. Again in year 4767 TC, the calendar system restarts and is called the New Era (the reference point being the year the Eldridge crashed onto the unnamed planet). PW continues on, stating the events of Xenogears begin in the year 9999 of the New Era. Whether year 0 is counted in any of the calendar systems is up for debate therefore leading to the disparity in the beginning of the events of the game.
BPL is the call sign of the official long-wave time signal service of the People's Republic of China, operated by the Chinese Academy of Sciences, broadcasting on 100 kHz from CAS's National Time Service Center in Pucheng County, Shaanxi at 34°56′54″N 109°32′34″E, roughly 70 km northeast of Lintong, along with NTSC's short-wave time signal BPM on 2.5, 5.0, 10.0, and 15.0 MHz.
BPL broadcasts LORAN-C compatible format signal from 5:30 to 13:30 UTC, using an 800 kW transmitter covering a radius up to 3000 km.
Chronometry (from Greek χρόνος chronos, "time" and μέτρον metron, "measure") is the science of the measurement of time, or timekeeping. Chronometry applies to electronic devices, while horology refers to mechanical devices.
It should not to be confused with chronology, the science of locating events in time, which often relies upon it.
A clock position is the relative direction of an object described using the analogy of a 12-hour clock to describe angles and directions. One imagines a clock face lying either upright or flat in front of oneself, and identifies the twelve hour markings with the directions in which they point.
Using this analogy, 12 o'clock means ahead or above, 3 o'clock means to the right, 6 o'clock means behind or below, and 9 o'clock means to the left. The other eight hours refer to directions that are not directly in line with the four cardinal directions.
In aviation, a clock position refers to a horizontal direction; it may be supplemented with the word high or low to describe the vertical direction which is pointed towards your feet. 6 o'clock high means behind and above the horizon, while 12 o'clock low means ahead and below the horizon.
A common year is a calendar year with 365 days, as distinguished from a leap year, which has 366. More generally, a common year is one without intercalation. The Gregorian calendar, (like the earlier Julian calendar), employs both common years and leap years to keep the calendar aligned with the tropical year, which does not contain an exact number of days.
The common year of 365 days has 52 weeks and one day, hence a common year always begins and ends on the same day of the week (for example, January 1 and December 31 fell on a Sunday in 2017) and the year following a common year will start on the subsequent day of the week. In common years, February has four weeks, so March will begin on the same day of the week. November will also begin on this day.
In the Gregorian calendar, 303 of every 400 years are common years. By comparison, in the Julian calendar, 300 out of every 400 years are common years, and in the Revised Julian calendar (used by Greece) 682 out of every 900 years are common years.
Endurantism or endurance theory is a philosophical theory of persistence and identity. According to the endurantist view, material objects are persisting three-dimensional individuals wholly present at every moment of their existence, which goes with an A-theory of time. This conception of an individual as always present is opposed to perdurantism or four dimensionalism, which maintains that an object is a series of temporal parts or stages, requiring a B-theory of time. The use of "endure" and "perdure" to distinguish two ways in which an object can be thought to persist can be traced to David Lewis.
HD2IOA is the callsign of a time signal radio station operated by the Navy of Ecuador. The station is located at Guayaquil, Ecuador and transmits in the HF band on 3.81 and 7.6 MHz.The transmission is in AM mode with only the lower sideband (part of the time H3E and the rest H2B/H2D) and consists of 780 Hz tone pulses repeated every ten seconds and voice announcements in Spanish.
While sometimes this station is described as defunct, reception reports of this station on 3.81 MHz appear regularly at the Utility DX Forum.
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of both days and months.
The minute is a unit of time or angle. As a unit of time, the minute is most of times equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). As a unit of angle, the minute of arc is equal to 1⁄60 of a degree, or 60 seconds (of arc). Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both. The SI symbols for minute or minutes are min for time measurement, and the prime symbol after a number, e.g. 5′, for angle measurement. The prime is also sometimes used informally to denote minutes of time.
The specious present is the time duration wherein one's perceptions are considered to be in the present. Time perception studies the sense of time, which differs from other senses since time cannot be directly perceived but must be reconstructed by the brain.
Tempus fugit is a Latin phrase, usually translated into English as "time flies". The expression comes from line 284 of book 3 of Virgil's Georgics, where it appears as fugit inreparabile tempus: "it escapes, irretrievable time". The phrase is used in both its Latin and English forms as a proverb that "time's a-wasting". Tempus fugit, however, is typically employed as an admonition against sloth and procrastination (cf. carpe diem) rather than a motto in favor of licentiousness (cf. "gather ye rosebuds while ye may"); the English form is often merely descriptive: "time flies like the wind", "time flies when you're having fun".
The phrase's full appearance in the Georgics is:
The phrase is a common motto, particularly on sundials and clocks.
Tomorrow is a temporal construct of the relative future; literally of the day after the current day (today), or figuratively of future periods or times. Tomorrow is usually considered just beyond the present and counter to yesterday. It is important in time perception because it is the first direction the arrow of time takes humans on Earth.
Y3S was the callsign of an East German time signal station. The station was operated by the Measurements and Standards Service of the DDR in Berlin. The transmitter was located at Nauen Transmitter Station.
The station transmitted in the HF band on 4.525 MHz with 5 kW. The transmission consisted of second pulses of 100 ms duration. Minute pulses were 500 ms long. Minute and hour information was transmitted in BCD code by modifying pulses of seconds 41 to 55. The vernerl time signal was transmitted on long wave from East Berlin at 11 55 for 5 minutes
YVTO is the callsign of the official time signal from the Juan Manuel Cagigal Naval Observatory in Caracas, Venezuela. The content of YVTO's signal, which is a continuous 1 kW amplitude modulated carrier wave at 5.000 MHz, is much simpler than that broadcast by some of the other time signal stations around the world, such as WWV.
The methods of time transmission from YVTO are very limited. The broadcast employs no form of digital time code. The time of day is given in Venezuelan Standard Time (VET), and is only sent using Spanish language voice announcements. YVTO also transmits 100 ms-long beeps of 1000 Hz every second, except for thirty seconds past the minute. The top of the minute is marked by a 0.5 second 800 Hz tone.The station previously broadcast on 6,100 MHz but appears to have changed to the current frequency by 1990.
