(Edit: As haukex mentions below, DateTime has date/time "mathematics" methods, if you need them. It wasn't clear to me from your question whether you need that or whether you are wanting to know the difference between the hour components of your dates, which is what I show here.)

Try something simpler.

use strict; use warnings; use feature 'say'; use DateTime::Format::Strptime; my $parser = DateTime::Format::Strptime->new( pattern => '%F %T', ); my $now = DateTime->now->hour; my $evt = $parser->parse_datetime('2017-06-15 13:14:31')->hour; my $diff = $now - $evt; say "now: $now"; say "evt: $evt"; say "diff: $diff"; __END__
Output:
$ perl 1193762.pl now: 7 evt: 13 diff: -6

Hope this helps!


The way forward always starts with a minimal test.
