On English-written materials, Indonesians tend to use the M-D-Y but was more widely used in non-governmental contexts. [citation needed] English-language governmental and academic documents use DMY. Iran: Yes: Yes: No: Short format: yyyy/mm/dd [80] in Persian Calendar system ("yy/m/d" is a common alternative). Gregorian dates follow the same ...
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data.It is maintained by the International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022.

In communications messages, a date-time group (DTG) is a set of characters, usually in a prescribed format, used to express the year, the month, the day of the month, the hour of the day, the minute of the hour, and the time zone, if different from Coordinated Universal Time (UTC).
In the C# programming language, or any language that uses .NET, the DateTime structure stores absolute timestamps as the number of tenth-microseconds (10 −7 s, known as "ticks" [80]) since midnight UTC on 1 January 1 AD in the proleptic Gregorian calendar, [81] which would overflow a signed 64-bit integer on 14 September 29,228 at 02:48:05 ...
In U.S. military use, 24-hour time is traditionally written without a colon (1800 instead of 18:00). For exact hour times, they are referred to as "hundred", so 10:00 would be referred to as "ten hundred hours" and 11:00 as "eleven hundred hours", from the mathematical interpretation of the numeral sequence.
Identifier Description Time manipulation difftime: computes the difference in seconds between two time_t values : time: returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch).
Mission control center's board with time data, displaying coordinated universal time with ordinal date (without year) prepended, on October 22, 2013 (i.e.2013-295). An ordinal date is a calendar date typically consisting of a year and an ordinal number, ranging between 1 and 366 (starting on January 1), representing the multiples of a day, called day of the year or ordinal day number (also ...
It encodes times with values that differ by several seconds from the POSIX time values. A version of this system, in which the epoch was 1970-01-01T00:00:00 TAI rather than 1970-01-01T00:00:10 TAI, was proposed for inclusion in ISO C's time.h, but only the UTC part was accepted in 2011. [9] A tai_clock does, however, exist in C++20.
