Operating system: Win XP Pro / Suse 9.1
PHP version: 5.2.1
PHP Bug Type: Date/time related
Bug description: Incorrect GMT timestamp
Description:
------------
REFERS TO THE FOLLOWING PHP VERSIONS:
Windows: 4.3.8 Linux: 4.3.8
4.4.4
5.0.0
5.1.6
5.2.1
1. My Wndows PC uses as local time CET (GMT+01:00 Amsterdam, Berlin, Bern
Rome ....) for Germany and my Linux PC uses CET too.
So if we have 09:11:08(CET) GMT is 08:11:08. But gmmktime() returns under
PHP 4.3.8, 4.4.4 and 5.0.0 a timestamp for 10:11:08. That's wrong!
With 5.1.6 and 5.2.1 gmmktime() returns the same value as mktime() and
dsttime is now 1 instead of 0.
That's wrong, too!
Reproduce code:
---------------
<?php
echo time();
echo "\n";
$var1 = gmmktime();
echo "GMT:\t $var1";
echo "\n";
$var2 = mktime();
echo "Local:\t $var2";
echo "\n";
$gmdate = date("d.m.Y - H:i:s", $var1);
$localdate = date("d.m.Y - H:i:s", $var2);
echo "GMT-Time: $gmdate\n";
echo "Local-Time: $localdate";
echo "\n";
print_r(gettimeofday());
?>
Actual result:
--------------
