Given this string: "Fri, 09 Apr 2010 14:10:50 +0000" how does one convert it to a datetime object?
After doing some reading I feel like this should work, but it doesn't...
>>> from datetime import datetime >>> >>> str = 'Fri, 09 Apr 2010 14:10:50 +0000' >>> fmt = '%a, %d %b %Y %H:%M:%S %z' >>> datetime.strptime(str, fmt) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.6/_strptime.py", line 317, in _strptime (bad_directive, format)) ValueError: 'z' is a bad directive in format '%a, %d %b %Y %H:%M:%S %z' It should be noted that this works without a problem:
>>> from datetime import datetime >>> >>> str = 'Fri, 09 Apr 2010 14:10:50' >>> fmt = '%a, %d %b %Y %H:%M:%S' >>> datetime.strptime(str, fmt) datetime.datetime(2010, 4, 9, 14, 10, 50) But I'm stuck with "Fri, 09 Apr 2010 14:10:50 +0000". I would prefer to convert exactly that without changing (or slicing) it in any way.

This datetime object will have no timezone associated with it. Therefore assign the UTC timezone to this datetime object using replace(tzinfo=pytz. UTC) function. Convert the timezone of the datetime object to local timezone by calling the astimezone() function on datetime object.
The ToUniversalTime method converts a DateTime value from local time to UTC. To convert the time in a non-local time zone to UTC, use the TimeZoneInfo. ConvertTimeToUtc(DateTime, TimeZoneInfo) method. To convert a time whose offset from UTC is known, use the ToUniversalTime method.
Use the pytz module, which comes with a full list of time zones + UTC. Figure out what the local timezone is, construct a timezone object from it, and manipulate and attach it to the naive datetime. Finally, use datetime. astimezone() method to convert the datetime to UTC.
It looks as if strptime doesn't always support %z. Python appears to just call the C function, and strptime doesn't support %z on your platform.
Note: from Python 3.2 onwards it will always work.
