While the Internet does have a tradition of accepting reality when creating specifications, this should not be done at the expense of interoperability.

Programs wishing to robustly deal with dates generated by such broken software should detect non-numeric decades and interpret appropriately.Ī number of devices currently connected to the Internet run their internal clocks in local time and are unaware of UTC. This occurs if the program simply subtracts 1900 from the year and adds the decade to the US-ASCII character zero.

It is possible that a program using two digit years will represent years after 1999 as ":0", ":1".

Programs wishing to robustly deal with dates generated by such broken software may add 1900 to three digit years. This occurs if the program simply subtracts 1900 from the year and doesn't check the number of digits.

It is possible that a program using two digit years will represent years after 1999 as three digits.

if used only for logging or tracing purposes). If a 2-digit year is received, it should be accepted ONLY if an incorrect interpretation will not cause a protocol or processing failure (e.g.

The use of 2-digit years is deprecated.

Internet Protocols MUST generate four digit years in dates.

The following requirements are to address the problems of ambiguity of 2-digit years: ¶ Z A suffix which, when applied to a time, denotes a UTC offset of 00:00 often spoken "Zulu" from the ICAO phonetic alphabet representation of the letter "Z". Timestamp This term is used in this document to refer to an unambiguous representation of some instant in time.

Internet Date/Time Format The date format defined in section 5 of this document. Email Date/Time Format The date/time format used by Internet Mail as defined by RFC 2822. ABNF Augmented Backus-Naur Form, a format used to represent permissible strings in a protocol or language, as defined in. divisible by one hundred) it shall also be divisible by four hundred an integral number of times. A leap year is a year whose number is divisible by four an integral number of times, except that if it is a centennial year (i.e. leap year In the Gregorian calendar, a year which has 366 days. However, see also the restrictions in Section 5.7 and Appendix D for how leap seconds are denoted within minutes. It is defined as the duration of 9,192,631,770 cycles of microwave light absorbed or emitted by the hyperfine transition of cesium-133 atoms in their ground state undisturbed by external fields. second A basic unit of measurement of time in the International System of Units.

UTC Coordinated Universal Time as maintained by the Bureau International des Poids et Mesures (BIPM). Description of time periods, or intervals, is not covered here. Date and time expressions indicate an instant in time.Such timestamps are expressed relative to universal time, using the best available practice at the stated time. Timestamps can express times that occurred before the introduction of UTC.This specification steers well clear of such considerations.) The UTC time corresponding to 17:00 on 23rd March 2005 in New York may depend on administrative decisions about daylight savings time. (This is distinct from some usage in scheduling applications where a local time and location may be known, but the actual relationship to UTC may be dependent on the unknown or unknowable actions of politicians or administrators. All times expressed have a stated relationship (offset) to Coordinated Universal Time (UTC).

All dates and times are assumed to be in the "current era", somewhere between 0000AD and 9999AD.This limited consideration has the following consequences: ¶ There are many ways in which date and time values might appear in Internet protocols: this document focuses on just one common usage, viz.
