Hello esteemed PerlMonks,

I have a list of time strings in the HH:MM:SS format. I want to add each to a variable set with localtime and compare it to a timestamp later in the script. I'm having trouble understanding how to add that HH:MM:SS string to the localtime variable.

#! /usr/bin/perl

use Time::Piece;
use strict;

my(@times) = ("00:05:21","00:08:05","00:10:33");

my $startTime = localtime();

print "Start: ", $startTime, $/;

foreach my $t (@times) {
    sleep 2;
    my $newTime = localtime();
    my $ss = $startTime + $t;     ### this is where I need advice
    if($ss > $newTime){
        print "\$ss is greater.\n";
                ### execute some functions here
    }

    print "Newtime: ", $newTime, $/;
    my $diff = $newTime - $startTime;
    print $diff, $/;

The $diff part works but not the addition of $t, how do I add that time to it? Obviously I need to convert it to something Time::Piece understands.

Thank you.
