Indeed, it cannot work, because parsing RFC 3. The format strings used by Python's datetime module are incapable of describing RFC 3. The problem is UTC offsets. The RFC 3. 33. 9 Internet Date/Time Format requires that every date- time includes a UTC offset, and that those offsets can either be Z (short for . A complete list of the directives they support can be found at https: //docs. UTC offset directive included in the list is %z: %z. UTC offset in the form +HHMM or - HHMM (empty string if the the object is naive). Example: (empty), +0. This doesn't match the format of an RFC 3. RFC 3. 33. 9 date, we'll fail: > > > from datetime import datetime. In Python 2 we'll fail for an even simpler reason, which is that strptime does not implement the %z directive at all in Python 2.)The multiple answers here that recommend strptime all work around this by including a literal Z in their format string, which matches the Z from the question asker's example datetime string (and discards it, producing a datetime object without a timezone): > > > datetime. But more importantly, because this approach involves hard- coding a particular UTC offset into the format string, it will choke the moment it tries to parse any RFC 3. UTC offset: > > > datetime. Use one of the many other approaches described in answers here instead. Pyiso8601: ISO 8601 Parsing for Python. 2007-01-14T20:34:22+00:00) into datetime objects. Datetimes and Timedeltas work together to provide ways for. The parser in NumPy 1.7 is quite strict about only accepting ISO. Using the ISO8601 parser. Automatic detection of ISO format. Parsing Dates and Times from Strings. ECMAScript revision 5 adds native support for simplified ISO 8601 dates in the Date.parse method, but some browsers currently on the market (Safari 5- IE 8- Firefox. Python 2.3 added a number of simple date and time types in the datetime module. There's no support for parsing strings in various formats and returning a.
