How to compare string date time in perl?

Question

Here\'s what I want:

Compare two date time strings like.

Answer 1

One more solution that uses the overloaded comparisons after converting the times to Time::Piece objects. Creating the objects may be overkill for something simple, but they can become very useful if you need to do other things with the times.

use Time::Piece;

my $dateformat = "%H:%M:%S, %m/%d/%Y";

my $date1 = "11:56:41, 11/22/2011";
my $date2 = "11:20:41, 11/20/2011";

$date1 = Time::Piece->strptime($date1, $dateformat);
$date2 = Time::Piece->strptime($date2, $dateformat);

if ($date2 < $date1) {
    do something...
} else {
    do nothing...
}
