#40744 [NEW]: possible mktime bug?

From: jeffkoston22 at yahoo dot com Operating system: Slackware 11 PHP version: 5.2.1 PHP Bug Type: Date/time related Bug description: possible mktime bug? Description: ------------ I'm not really fond of mktime() but I needed a way of taking two dates in MySQL format and seeing which date is older... ie: $date = "2007-03-01"; if ($date <= date('Y-m-d')) { print "Expired"; } else { print "Not Expired"; } I know you can't use dates like that in the condition so I used date('U') and mktime() to give me the seconds since the Unix Epoch but I decided to test using different date formats first just to see how mktime handles months and years that might or might not have leading zero's.. notice the difference in seconds with the year 08 vs. 07 please correct me if I'm doing something stupid here that I should not be doing. 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)) .
