Re: Best way to compare date strings

Use the DateTime family of modules.

#!/usr/bin/perl

use strict;
use warnings;
use DateTime::Format::Strptime;

my $fmt = DateTime::Format::Strptime->new(pattern => '%Y/%m/%d %H:%M:%
+S:%3N');

my $date1 = $fmt->parse_datetime('2006/01/03 03:59:59:671');
my $date2 = $fmt->parse_datetime('2006/01/03 04:00:00:562');

my $diff = $date2 - $date1;

print $diff->in_units('nanoseconds'), "\n";

It looks like you might have cut and pasted the code from your browser instead of using the 'download' link. That will add extra '+' characters into the code where it get split on a line break. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]
