Bug description:mktime returns wrong date if used zero prefix in day
Description:
------------
When used mktime() with parameters with zero prefix in days 2011-01-08 and
2011-01-09 the function returns timestamp for GMT: Thu, 30 Dec 2010
23:00:00 GMT
Example: note zeros in month and day parameters
mktime(0,0,0,01,08,2011)) returns wrong date GMT: Thu, 30 Dec 2010 23:00:00
GMT
mktime(0,0,0, 1,08,2011)) returns wrong date GMT: Thu, 30 Dec 2010 23:00:00
GMT
mktime(0,0,0, 1, 8,2011)) returns correct date
mktime(0,0,0,01, 8,2011)) returns correct date
Test script:

date_default_timezone_set('Europe/Prague');

mktime(0,0,0,1,8,2011), " WR\r\n";
echo "2011-01-9 => ", date('Y-m-d', mktime(0,0,0,01,9,2011)), " ",

echo "2011-01-10 => ", date('Y-m-d', mktime(0,0,0,01,10,2011)), " ",
mktime(0,0,0,1,10,2011), " OK\r\n";
Expected result:
----------------
In the test script above you can compare initial date and returned date. In
my case for days 08 and 09 it returned date of 2010-12-31 which is wrong.
