Bug#666502: python-tz: returns incorrect UTC offsets

[Rémy Oudompheng]

Package: python-tz
Version: 2010b-1
Severity: grave
Tags: upstream
Justification: renders package unusable

In a Python shell (on 30 Mar 2012):

>>> import datetime, pytz
>>> now = datetime.datetime.now()
>>> pytz.timezone("US/Hawaii").utcoffset(now)
datetime.timedelta(-1, 48600)

The expected answer is datetime.timedelta(-1, 50400).
The bug is known upstream and was corrected in a later
version. Since timezones and offsets are the main usage
of python-tz, this makes the package unusable.
