gmtime
Synopsis
gmtime expr
Converts a time string as returned by the time function to a nine-element list
with the time correct for Greenwich Mean Time zone (a.k.a. GMT,
UTC, etc.). Typically used as follows:
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
gmtime(time);All list elements are numeric and come straight out of a C
language struct tm. In
particular, this means that $mon has the range 0..11, $wday has the range 0..6, and the year has had 1,900
subtracted from it. (You can remember which elements are 0-based because you’re always using
these as subscripts into 0-based arrays containing month and day
names.) If expr is omitted, it does
gmtime(time). For example, to
print the current month in London:
$london_month = (qw(Jan Feb Mar Apr May Jun
Jul Aug Sep Oct Nov Dec))[(gmtime)[4]];The Perl library module Time::Local contains a subroutine,
timegm( ), that can convert in
the opposite direction.
In scalar context, gmtime
returns a ctime(3)-like string
based on the GMT time value.
