Here\'s what I want:

Compare two date time strings like.

$date1 = \"11:56:41         


        

Answer 1

I use unixtime. :)

I convert both times to unixtime and then I just have two integers to compare and so I can use the operators <, ==, > etc

e.g. convert to unixtime as follows

my $timestamp = "2014-03-25 12:33:32";  # (We assume localtime)

# 
# To split on the space character, it's best to use the regex / /
# 
my ($date, $time) = split (/ /, $timestamp);
my ($year, $mon, $mday) = split ('-', $date);
my ($hour, $min, $sec) = split (':', $time);

my $unixtime = timelocal($sec, $min, $hour, $mday, $mon-1, $year);
