RE: [PHP] Weird mktime problem

You might want to consider removing the leading zeroes, this post is there in the php manual and has been useful to me. ---------xxx----------------------------- jchen3625 AT yahoo DOT com (25-Aug-2002 03:33) beware, arguments with leading zeros are treated as zeros. that is, "mktime(0,0,0,10,09,2002)" == 09/30/2002, whereas "mktime(0,0,0,10,9,2002)" == 10/09/2002. ---------xxx----------------------------- Naintara -----Original Message----- From: php-general-return-152942-naintara=del6.vsnl.net.in@lists.php.net [mailto:php-general-return-152942-naintara=del6.vsnl.net.in@lists.php.ne t]On Behalf Of Ford, Mike [LSS] Sent: Thursday, June 26, 2003 3:23 PM To: 'Glenn'; php-general@lists.php.net Subject: RE: [PHP] Weird mktime problem > -----Original Message----- > From: Glenn [mailto:WaterDios@yahoo.com] > Sent: 25 June 2003 14:58 [....] > Here is what's weired. > > I use these lines to get the specifics: > $StartHour = substr("$StartTime", 0, 2); > $StartMinute = substr("$StartTime", 3, 2); > $EndHour = substr("$EndTime", 0, 2); > $EndMinute = substr("$EndTime", 3, 2); > list($SMonth, $SDay, $SYear) = split('/', $StartDate); > list($EMonth, $EDay, $EYear) = split('/', $EndDate); > > I then do this: > $SUnixTime = mktime($StartHour, $StartMinute, 00, $SMonth, > $SDay, $SYear); > > This is what's being sent to the mktime: > (17,00,00,06,23,2003) > > This is what it ouputs: > 1056405600 > > Which is not technically correct.

UNIX timestamps are *always* GMT -- it's the routines that process them that do timezone (and DST) conversion. To prove this, run the following on your server: <?php $timestamp = 1056405600; echo "GMT = ", gmdate("Y-m-d H:i:s"), "<br />\n"; echo "local = ", date("Y-m-d H:i:s"), "<br />\n"; ?> Also see the manual page for gmdate() at http://www.php.net/gmdate which shows a very similar script as its first example.
