Issue2162

1) Day/month with 00 value is accepted:
 
    Jython 2.5.3 (2.5:c56500f08d34+, Aug 13 2012, 14:48:36) 
    [Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_55

    >>> import time, datetime
    >>> time.strptime('0000-00-00 00:00:00', '%Y-%m-%d %H:%M:%S')
    (2, 11, 30, 0, 0, 0, 6, 334, -1)
    >>> datetime.datetime.strptime('0000-00-00 00:00:00', '%Y-%m-%d %H:%M:%S')
    datetime.datetime(2, 11, 30, 0, 0)

With CPython both of the above yield this error:

    ValueError: time data '0000-00-00 00:00:00' does not match format '%Y-%m-%d %H:%M:%S'


2) String not matching pattern is accepted:

    >>> time.strptime('11:59 02-06-2014', '%H:%M %d-%m')
    (1970, 6, 2, 11, 59, 0, 1, 153, -1)
    >>> datetime.datetime.strptime('11:59 02-06-2014', '%H:%M %d-%m')
    datetime.datetime(1970, 6, 2, 11, 59)

With CPython you get:

    ValueError: unconverted data remains: -2014

The latter (2) has been addressed in Jython 2.7.x, I believe.

Per Santoso, this has been fixed for some time in 2.7, and it's not something we would backport to 2.5
