in reply to setting limitations for users based on time

Welcome, please read and understand How do I post a question effectively?, it's better if you show people what you tried and explain how it failed. Below is an example of what I think you're looking for.

#!/usr/bin/perl use strict; use warnings; use DateTime; my $dt = DateTime->now; my $minute = $dt->minute; if ( $minute >= 55 ){ print "It's within 5 minutes of an hour\n"; }else{ print "No clock in for you!\n"; }
