offset_as_string, a patch

[kellan]

There is a minor bug in offset_as_string, when calculating the offset for
negative timezones.

If you pass in the timezone -05:00, offset_as_string returns -19:00 this
is because, according to Perl, -5%24 == 19.

the solution is to change $hours %= 24 to $hours = abs($hours) % 24;

I've attached a patch.

Thanks,
kellan
