This sounds like a simple case of string munging 
use strict;

my $seconds = 0;
my $timestr = '5H3M17S';

my ($hr,$min,$sec) =
$timestr =~ /^(?:(\d+)H)?(?:(\d)+M)?(\d+)S$/;


$seconds += $hr  * 60 * 60 if defined $hr;
$seconds += $min * 60      if defined $min;
$seconds += $sec;

print "seconds left to going live - $seconds";

Pretty simple stuff really, just grab what's there, do a few multiplications and your set.
