The last modification date stamp (and with DELWATCH 2.0+ also the file deletion date stamp, and since DOS 7.0+ optionally also the last access date stamp and creation date stamp), are stored in the directory entry with the year represented as an unsigned seven bit number (0–127), relative to 1980, and thereby unable to indicate any dates in ...
TIME WITH TIME ZONE: the same as TIME, but including details about the time zone in question. TIMESTAMP : This is a DATE and a TIME put together in one variable (e.g. 2011-05-03 15:51:36.123456 ). TIMESTAMP WITH TIME ZONE : the same as TIMESTAMP , but including details about the time zone in question.
National standard format is yyyy-mm-dd. [161] dd.mm.yyyy format is used in some places where it is required by EU regulations, for example for best-before dates on food [162] and on driver's licenses. d/m format is used casually, when the year is obvious from the context, and for date ranges, e.g. 28-31/8 for 28–31 August.
RFC 3339 Date and Time on the Internet: Timestamps specifies YYYY-MM-DD, i.e. a particular subset of the options allowed by ISO 8601. [10] RFC 5322 Internet Message Format specifies day month year where day is one or two digits, month is a three letter month abbreviation, and year is four digits. [11]
A time interval is the intervening time between two time points. The amount of intervening time is expressed by a duration (as described in the previous section). The two time points (start and end) are expressed by either a combined date and time representation or just a date representation. There are four ways to express a time interval:
Convert a year to two digits with zero padding, but years ending in 00 are returned with all digits and no leading zeros. Tests 1999 -> 99 2000 -> 2000 2001 -> 01 See also. Template:Two-digit year. Will also convert years ending in 00.
While using 3-digit years and 3-digit dates within that year was used by some, others chose to use the number of days since a fixed date, such as 1 January 1900. [26] Inaction was not an option, and risked major failure. Embedded systems with similar date logic were expected to malfunction and cause utilities and other crucial infrastructure to ...
Although non-abbreviated years are generally preferred, two-digit ending years (1881–82, but never 1881–882 or 1881–2) may be used in any of the following cases: (1) two consecutive years; (2) infoboxes and tables where space is limited (using a single format consistently in any given table column); and (3) in certain topic areas if there ...
