I don't quite understand Bug #25050 - is this the same situation? thanks for your time! Reproduce code: --------------- print "test1: " . date('U', mktime(0, 0, 0, 3, 1, 2008)) . "<br />"; // 3-1-2008 returned 1204261200 print "test2: " . date('U', mktime(0, 0, 0, 3, 1, 08)) . "<br />"; // 3-1-08 returned 951800400 print "test3: " . date('U', mktime(0, 0, 0, 03, 1, 2008)) . "<br />"; // 03-1-2008 returned 1204261200 print "test4: " . date('U', mktime(0, 0, 0, 03, 1, 08)) . "<br />"; // 03-1-08 returned 951800400 print "test5: " . date('U', mktime(0, 0, 0, 3, 1, 2007)) . "<br />"; // 3-1-2007 returned 1172638800 print "test6: " . date('U', mktime(0, 0, 0, 3, 1, 07)) . "<br />"; // 3-1-07 returned 1172638800 print "test7: " . date('U', mktime(0, 0, 0, 03, 1, 2007)) .
