Timestamp difference calculation

swami has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I was trying to calculate the time difference b/w two input timestamp in perl. But i am not getting the value. Should i do any formatting of input paramters.

#!/usr/bin/perl

use POSIX;
my $ts1 = "$ARGV[0]";
my $ts2 = "$ARGV[1]";

$diff = ($ts1 - $ts2);
print int($diff);

G'day swami, Welcome to the monastery. You'll need to show us your input as well as the actual and expected output. Guidelines for this are given in: How do I post a question effectively? There are lots of date-related modules on CPAN; for instance, Date::Calc might be appropriate for your needs. -- Ken	[reply]

Hello swami, welcome to the Monastery. Please, wrap your code sample into `<code> ... </code>` tags. See Markup in the Monastery. What is the expected format of the input? Plese, show example input and expected output. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]

Hi, "... I was trying to calculate the time difference b/w two input timestamp in perl..." Please, I don't see how you are doing that here. However, in the first place, you might want to properly placed your script in code tags see How do I post a question effectively? Then, in the code you posted, I believe you intented `$ARGV[1]` NOT `$ARGV1` If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply] [d/l] [select]
