{} – works with "fuzzy" or ambiguous dates {{Birth date and age}} – used on most biographical entries {{Birth date and age2}} – calculates age at a specified date {{Birth based on age as of date}} – used when a reference mentions the age of a person as of the date of the reference's publication {{Birth year and age}} {}
A distinction is sometimes made between the terms datestamp, timestamp and date-timestamp: Datestamp or DS : A date, for example 2025-02-4 according to ISO 8601 Timestamp or TS : A time of day, for example 15:12:28 using 24-hour clock
System time is measured by a system clock, which is typically implemented as a simple count of the number of ticks that have transpired since some arbitrary starting date, called the epoch. For example, Unix and POSIX -compliant systems encode system time (" Unix time ") as the number of seconds elapsed since the start of the Unix epoch at 1 ...
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.
Many computer systems measure time and date using Unix time, an international standard for digital timekeeping. Unix time is defined as the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (an arbitrarily chosen time based on the creation of the first Unix system), which has been dubbed the Unix epoch. [6]
Unix time [a] is a date and time representation widely used in computing. It measures time by the number of non-leap seconds that have elapsed since 00:00:00 UTC on 1 January 1970, the Unix epoch. For example, at midnight on 1 January 2010, Unix time was 1262304000. Unix time originated as the system time of Unix operating systems.
A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used. [3] To help compare orders of magnitude of different times , this page lists times between 10 −3 seconds and 10 0 seconds (1 milli second and one second).
-- The logic of PHP mktime is followed where m or d can be zero to mean-- the previous unit, and -1 is the one before that, etc.-- Positive values carry forward. local date if not (1 <= m and m <= 12) then date = Date (y, 1, 1) if not date then return end date = date + ((m-1).. 'm') y, m = date. year, date. month end local days_hms if not ...
