Try this module Time::Piece

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards compatible manner, so that using localtime/gmtime in the way documented in perlfunc will still return what you expect

you can also able find time different 

$t1 - $t2; # returns Time::Seconds object
$t1 - 42; # returns Time::Piece object
$t1 + 533; # returns Time::Piece object
