fromutc: dt.tzinfo is not self: pytz.timezone('UTC').fromutc(datetime.utcnow())

[aspineux]

hi

import pytz
from datetime import datetime
pytz.timezone('GMT0').fromutc(datetime.utcnow())

datetime.datetime(2011, 10, 19, 7, 54, 45, 579125,
tzinfo=<StaticTzInfo 'GMT0'>)

pytz.timezone('UTC').fromutc(datetime.utcnow())

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: fromutc: dt.tzinfo is not self

pytz.timezone('Europe/Brussels').fromutc(datetime.utcnow())

datetime.datetime(2011, 10, 19, 9, 55, 47, 787937, tzinfo=<DstTzInfo
'Europe/Brussels' CEST+2:00:00 DST>)

Why does UTC fail ?
Bug or feature ?

Dunno, but it might be worth noting that the examples in the pytz docs
don't use .fromutc(). Have you tried using .localize() instead? Or
specifically in the case of UTC,
datetime.utcnow().replace(tzinfo=pytz.utc) ?

Cheers,
Chris

Looks like a bug to me. But I'm not an expert on pytz. Perhaps you should
report it back to the package author.
