If convenience is more important than size (`Date::Manip` is about 240k of Perl code), you could do `use Date::Manip; my $time = UnixDate('2007/07/17 13:21', "%s"); print "time=$time\n"; # 1184671260` [download]	[reply] [d/l] [select]

How about Date::Parse and its str2time function? Phil The Gantry Web Framework Book is now available.	[reply]

Well, not for all "like" strings, but for exactly that format, I'd do something like `use Time::Local; my $str = '2007/07/17 13:21'; my @t = $str =~ m!(\d{4})/(\d{2})/(\d{2})\s(\d{2}):(\d{2})!; $t[1]--; my $timestamp = timelocal 0,@t[4,3,2,1,0]; # verify... print scalar localtime $timestamp; __END__ Tue Jul 17 13:21:00 2007` [download] before looking up any module of CPAN. Things would be different if I had to convert disparate formats. --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

DateTime is also up for the job. `use strict; use warnings; use DateTime::Format::Strptime; my $str = '2007/07/17 13:21'; my $parser = DateTime::Format::Strptime->new( pattern => '%Y/%m/%d %H:%M' ); my $dt = $parser->parse_datetime( $str ); print $dt->epoch; __END__ C:\src\perl\perlmonks\627080>perl -w 627080.pl 1184678460` [download] -- Andreas	[reply] [d/l]

Really? I've been referring to these as a date string and a unix timestamp.	[reply]
