Date::Calc Vivek -- In accordance with the prarabdha of each, the One whose function it is to ordain makes each to act. What will not happen will never happen, whatever effort one may put forth. And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.	[reply]

What output you need to show. Whether the difference b/w two time or after subtraction? Moreover what you have tried so for? so that we can provide guidelines to you. --Lakshmanan G. The great pleasure in my life is doing what people say you cannot do.	[reply]

There are 60 seconds in a minute and 60 minutes in an hour. A quick glance at Multiplicative Operators and a little ingenuity should see you through. Cheers, JohnGG	[reply]

Try this.. `#!/usr/bin/perl use strict; use Date::Manip; my $time_a = "12:00:00"; my $time_b = "11:10:00"; my $delta = DateCalc( $time_a, $time_b ); print join ":", ( (split( ":", $delta ))[4, 5, 6] );` [download]	[reply] [d/l]
