datetime – Parsing time string in Python

datetime – Parsing time string in Python

datetime.datetime.strptime has problems with timezone parsing. Have a look at the dateutil package:

>>> from dateutil import parser
>>> parser.parse(Tue May 08 15:14:45 +0800 2012)
datetime.datetime(2012, 5, 8, 15, 14, 45, tzinfo=tzoffset(None, 28800))

Your best bet is to have a look at strptime()

Something along the lines of

>>> from datetime import datetime
>>> date_str = Tue May 08 15:14:45 +0800 2012
>>> date = datetime.strptime(date_str, %a %B %d %H:%M:%S +0800 %Y)
>>> date
datetime.datetime(2012, 5, 8, 15, 14, 45)

Im not sure how to do the +0800 timezone unfortunately, maybe someone else can help out with that.

The formatting strings can be found at http://docs.python.org/library/time.html#time.strftime and are the same for formatting the string for printing.

Hope that helps

PS, Your best bet for timezones in installing pytz from pypi. ( http://pytz.sourceforge.net/ )
in fact I think pytz has a great datetime parsing method if i remember correctly. The standard lib is a little thin on the ground with timezone functionality.

Heres a stdlib solution that supports a variable utc offset in the input time string:

>>> from email.utils import parsedate_tz, mktime_tz
>>> from datetime import datetime, timedelta
>>> timestamp = mktime_tz(parsedate_tz(Tue May 08 15:14:45 +0800 2012))
>>> utc_time = datetime(1970, 1, 1) + timedelta(seconds=timestamp)
>>> utc_time
datetime.datetime(2012, 5, 8, 7, 14, 45)
