Perl Time Related Functions


gmtime(EXPR)
gmtime EXPR
gmtime
Converts a time as returned by the time function to a 9-element array with the time analyzed for the Greenwich timezone. Typically used as follows:

($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)
= gmtime(time);

All array elements are numeric, and come straight out of a `struct tm'. In particular this means that $mon has the range `0..11' and $wday has the range `0..6'. If EXPR is omitted, does `gmtime(time)'.
localtime(EXPR)
localtime EXPR
localtime
Converts a time as returned by the time function to a 9-element array with the time analyzed for the local timezone. Typically used as follows:

($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)
= localtime(time);

All array elements are numeric, and come straight out of a `struct tm'. In particular this means that $mon has the range `0..11' and $wday has the range `0..6'. If EXPR is omitted, does localtime(time).
time
Returns the number of non-leap seconds since 00:00:00 UTC, January 1, 1970. Suitable for feeding to gmtime() and localtime().
