NO!

If you only use GMT offsets you'll just annoy your users anywhere in the
world that has DST. If that's the only solution don't bother - just use a
relevant fixed timezone.

Much better to use the Olsen DB timezone names (DateTime supports them).

my $dt = DateTime->new( year => 2009,
                        month => 6,
                        day => 25,
                        hour => 15,
                        minute => 42,
                        time_zone => 'Europe/London');
print $dt->datetime, "\n";
$dt->set_time_zone('America/New_York');
print $dt->datetime, "\n";


As far as the original question - you could pass the user's choice of
timezone as a parameter when you call the model to request the time. So
instead of:

$object->creation_date->strftime(' ... ');
$object->creation_date($user->prefs->tz)->strftime(' ... ');

That still allows you to have a model that will work without being part of a
web request and that is easily testable.
