Pytz and strange timezones

Timezones are not easy. But with the pytz release 2014.3 it got even more insane.

For example:

>>> import pytz
>>> pytz.timezone('Europe/Berlin')
<DstTzInfo 'Europe/Berlin' LMT+0:53:00 STD>

LMT is for local mean time which was the timezone system till 1893.

After version 2014.3 of pytz you should not use tzinfo to set timezone:

>>> import pytz
>>> from datetime import datetime
>>> datetime(2014, 8, 29, 18, 0, tzinfo=pytz.timezone('Europe/Berlin'))
datetime(2014, 8, 29, 18, 0, tzinfo=<DstTzInfo 'Europe/Berlin' LMT+0:53:00 STD>)

now you really should use .localize() of your timezone object:

>>> import pytz
>>> from datetime import datetime
>>> pytz.timezone('Europe/Berlin').localize(datetime(2014, 8, 29, 18, 0))
datetime(2014, 8, 29, 18, 0, tzinfo=<DstTzInfo 'Europe/Berlin' CEST+2:00:00 DST>)
