[Vobject] no TZ info in parsed dates?

[Bill Janssen]

Hi.  I'm wondering why there's no timezone info in my parsed iCalendar
vevents?

Is there some initialization step I'm omitting?  This is vobject 0.8.1c
with Python 2.5 on OS X 10.5.7.

>>> e.contents.get("dtstart")
[<DTSTART{'X-VOBJ-ORIGINAL-TZID': [u'Pacific Standard Time']}2009-06-12 10:00:00>]
>>> e.dtstart.value
datetime.datetime(2009, 6, 12, 10, 0)
>>> e.dtstart.value.tzinfo
>>> e.dtstart.value.isoformat()
'2009-06-12T10:00:00'
