Now, if we subtract a few minutes from it, note that the timezone
|
||||
information has not changed.
|
||||
|
||||
>>> before = loc_dt - timedelta(minutes=10)
|
||||
>>> before.strftime(fmt)
|
||||
'2002-10-27 00:50:00 EST (-0500)'
|
||||
|

But we can fix that by calling the normalize method
|
||||
|
||||
>>> before = eastern.normalize(before)
|
||||
>>> before.strftime(fmt)
|
||||
'2002-10-27 01:50:00 EDT (-0400)'
|
||||
|
||||
The supported method of converting between timezones is to use
|
||||
datetime.astimezone(). Currently, normalize() also works:
|
||||
|
||||
>>> th = timezone('Asia/Bangkok')
|
||||
>>> am = timezone('Europe/Amsterdam')
|
||||
>>> dt = th.localize(datetime(2011, 5, 7, 1, 2, 3))
|
||||
>>> fmt = '%Y-%m-%d %H:%M:%S %Z (%z)'
|
||||
>>> am.normalize(dt).strftime(fmt)
|
||||
'2011-05-06 20:02:03 CEST (+0200)'
