Description:
------------
strptime returns random values for parts not included in the format string.

manpage of strptime says:
"In principle, this function does not initialize tm but  only stores the values specified. This means that tm should be initialized before the call."

But this isn't done in ext/standard/datetime.c
neither in 5.1.5 nor in 5.2.0RC2

Reproduce code:
---------------
// only date, no time given
print_r(strptime('2006-08-20', '%Y-%m-%d'));



Expected result:
----------------
Array
(
    [tm_sec] => 0
    [tm_min] => 0
    [tm_hour] => 0
    [tm_mday] => 20
    [tm_mon] => 7
    [tm_year] => 106
    [tm_wday] => 0
    [tm_yday] => 231
    [unparsed] => 
)


Actual result:
--------------
Array
(
    [tm_sec] => 140252532  <-- random values each time called
    [tm_min] => 13 <-- random values each time called
    [tm_hour] => 1 <-- random values each time called
    [tm_mday] => 20
    [tm_mon] => 7
    [tm_year] => 106
    [tm_wday] => 0
    [tm_yday] => 231
    [unparsed] => 
)
