issue 2166 - datetime.strptime does not support %f on Jython 2.7

Hi all,

I would like to make some contribution to the jython project. I browsed the
bug tracker and randomly picked this issue as a  starting point:
http://bugs.jython.org/issue2166

I think this is the cause of the bug:


In src/org/python/modules/time/Time.java, function 'private static PyTuple
pystrptime(String data_string, String format)' , it calls
_strptime._strptime_time to parse the data_string according to the format.
But this function does not understand '%f' flag.



 >>> from _strptime import _strptime_time

>>> _strptime_time('2014-06-16 17:03:58.483000', '%Y-%m-%d %H:%M:%S.%f')

time.struct_time(tm_year=2014, tm_mon=6, tm_mday=16, tm_hour=17, tm_min=3,
tm_sec=58, tm_wday=0, tm_yday=167, tm_isdst=-1)


If we call _strptime instead, we will get this result instead:

>>> from _strptime import _strptime

>>> _strptime('2014-06-16 17:03:58.483000', '%Y-%m-%d %H:%M:%S.%f')

(time.struct_time(tm_year=2014, tm_mon=6, tm_mday=16, tm_hour=17, tm_min=3,
tm_sec=58, tm_wday=0, tm_yday=167, tm_isdst=-1), 483000)


I am not sure what is the best way to fix this problem. Does it make sense
to switch to use _strptime when there is a %f flag presence? I would love
to hear some suggestions so I can learn more the jython codebase, and
hopefully, be able to patch it and give something back to the community.


Thanks, Tony
