* is_dst
    Returns a boolean indicating whether or not the datetime object is
    currently in Daylight Saving Time or not.

So something like this should give you what you need.

use strict;
use warnings;
use DateTime;

print DateTime->today( time_zone => 'America/Los_Angeles')->is_dst;

Hope this helps
