UTdate

Routine

char *UTdate (int format)

Purpose

Return a date/time string for the current time

Description

This routine returns a date/time string in a number of standard formats. Formats 0, 1 and 2 are in local time. Format 3 gives the date and time in GMT (Universal Coordinated Time).

Format 0 is the standard C-language format (without the trailing newline character). Format 1 includes the time zone abbreviation. Formats 0 and 1 use abbreviations for the day of the week and the month. Formats 2 and 3 avoid language dependent names (except for the time-zone code). 

 Format  Example                      time zone    typical length
   0    Sun Sep 16 01:03:52 1973      local time   24 + null
   1    Sun Sep 16 01:03:52 EST 1973  local time   28* + null
   2    1994-01-23 09:59:53 EST       local time   23* + null
   3    1994-01-23 14:59:53 UTC       GMT          23 + null
             (*) the time zone length can vary
