ISO 4031

ISO 4031 is an international standard first issued in 1978 by the International Organization for Standardization. It defined the representation of local time differentials, commonly referred to as time zones. It has since been superseded by a newer standard, ISO 8601.[1] This newer standard sets out the current formats for local time differentials and so ISO 4031 is no longer in use.

ISO 2014

ISO 2014 is an international standard that was issued in April 1976, and superseded by ISO 8601 in June 1988. ISO 2014 was the standard that originally introduced the all-numeric date notation [YYYY]-[MM]-[DD] with the digits in order starting with the most significant digit first (similar to big-endian). It was technically identical to ISO Recommendation R 2014 from 1971.

ISO 3307

ISO 3307 is an international standard for date and time representations issued by the International Organization for Standardization (ISO). The standard was issued in 1975, then was superseded by ISO 8601 in 1988.

ISO 8601

ISO 8601 Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date- and time-related data. It was issued by the International Organization for Standardization (ISO) and was first published in 1988. The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, so as to avoid misinterpretation of numeric representations of dates and times, particularly when data are transferred between countries with different conventions for writing numeric dates and times.

In general, ISO 8601 applies to representations and formats of dates in the Gregorian (and potentially proleptic Gregorian) calendar, of times based on the 24-hour timekeeping system (with optional UTC offset), of time intervals, and combinations thereof. The standard does not assign any specific meaning to elements of the date/time to be represented; the meaning will depend on the context of its use. In addition, dates and times to be represented cannot include words with no specified numerical meaning in the standard (e.g., names of years in the Chinese calendar) or that do not use characters (e.g., images, sounds).In representations for interchange, dates and times are arranged so the largest temporal term (the year) is placed to the left and each successively smaller term is placed to the right of the previous term. Representations must be written in a combination of Arabic numerals and certain characters (such as "-", ":", "T", "W", and "Z") that are given specific meanings within the standard; the implication is that some commonplace ways of writing parts of dates, such as "January" or "Thursday", are not allowed in interchange representations.
