Bug description:  more useful initialization for strptime 

Description:
------------
Hi,


in addition to bug #38524 I'd prefer initializing call to strptime in a
more useful way. While it is easiest way to memset all with 0's, some
fields like tm_mon can't be interpreted properly. 

My proposal uses 0xFF for initialization to get all values set -1.

Then in addition, I add array element value NULL on every field that
wasn't touched by strptime. I consider this to be quite common behaviour
in PHP ...

Below is my proposal for a patch on latest CVS snapshot.


Best Regards,

Thomas Urban
