As far as I can tell from running the following, it all seems to work as expected in python 3.2 (and hence I expect in 3.4). If the expected output doesn't match yours, it would be interesting to see what your output is. If the expected output does match yours, and you think it's wrong, it would be interesting to know which bits you think are wrong and why you think they are wrong, because having a fair bit of the night looking at this, it all looks good to me. #!/usr/bin/python3 from datetime import tzinfo, timedelta, datetime, timezone # define timedelta based timezones UTCm7 = timezone(timedelta(0,-7*3600),"UTC-07:00") UTCp7 = timezone(timedelta(0,+7*3600),"UTC+07:00") UTC = timezone(timedelta(0), "UTC+00:00") # some timestrings t1 = 'Sat, 09 Aug 2014 07:36:46 -0700' t2 = 'Sat, 09 Aug 2014 07:36:46 +0700' t3 = 'Sat, 09 Aug 2014 07:36:46 +0000' # make some datetime objects # these are both utc -7 a1 = datetime.strptime(t1,"%a, %d %b %Y %H:%M:%S %z") b1 = datetime(2014, 8, 9, 7, 36, 46, tzinfo = UTCm7) # these are both utc +7 a2 = datetime.strptime(t2,"%a, %d %b %Y %H:%M:%S %z") b2 = datetime(2014, 8, 9, 7, 36, 46, tzinfo = UTCp7) # these are both utc a3 = datetime.strptime(t3,"%a, %d %b %Y %H:%M:%S %z") b3 = datetime(2014, 8, 9, 7, 36, 46, tzinfo = UTC) # print them out as stored print( "UTC -7:" ) print( t1 ) print( a1 ) print( b1 ) print( "UTC +7:" ) print( t2 ) print( a2 ) print( b2 ) print( "UTC:" ) print( t3 ) print( a3 ) print( b3 ) # print them out converted to UTC print( "UTC -7 as UTC:" ) print( a1.astimezone( UTC ) ) print( b1.astimezone( UTC ) ) print( "UTC +7 as UTC:" ) print( a2.astimezone( UTC ) ) print( b2.astimezone( UTC ) ) print( "UTC as UTC:" ) print( a3.astimezone( UTC ) ) print( b3.astimezone( UTC ) ) # expected output """ UTC -7: Sat, 09 Aug 2014 07:36:46 -0700 2014-08-09 07:36:46-07:00 2014-08-09 07:36:46-07:00 UTC +7: Sat, 09 Aug 2014 07:36:46 +0700 2014-08-09 07:36:46+07:00 2014-08-09 07:36:46+07:00 UTC: Sat, 09 Aug 2014 07:36:46 +0000 2014-08-09 07:36:46+00:00 2014-08-09 07:36:46+00:00 UTC -7 as UTC: 2014-08-09 14:36:46+00:00 2014-08-09 14:36:46+00:00 UTC +7 as UTC: 2014-08-09 00:36:46+00:00 2014-08-09 00:36:46+00:00 UTC as UTC: 2014-08-09 07:36:46+00:00 2014-08-09 07:36:46+00:00 """ -- Denis McMahon, denismfmcma...@gmail.com -- https://mail.python.org/mailman/listinfo/python-list
