Description:
------------
I'm trying to use gmmktime() to convert a string (from database) containing date and time to managable date.

When the time (in the string) is 02:00:00 28 mars 2004 it's getting strange!

The error only occurs when the hour is 2, which is exactly when Daylight Saving Time should start in UTC+0100. When using 01:00:00 and 03:00:00 it works just fine. I consider this a bug, cause it make no sense.


Shortly:

The date from the database is saved in GMT-time and I want to KEEP IT that way. The reason I have to use gmmktime() is because of further necessary adjustments of the date!

Reproduce code:
---------------
<?php

echo "<br>1. ";
echo gmdate("Y-m-d H:i:s", gmmktime(02, 0, 0, 3, 27, 2004));
echo "<br>2. ";
echo gmdate("Y-m-d H:i:s", gmmktime(02, 0, 0, 3, 28, 2004));
echo "<br>3. ";
echo gmdate("Y-m-d H:i:s", gmmktime(02, 0, 0, 3, 29, 2004));
echo "<br>";

?>

Expected result:
----------------
1. 2004-03-27 02:00:00
2. 2004-03-28 02:00:00
3. 2004-03-29 02:00:00

Actual result:
--------------
1. 2004-03-27 02:00:00
2. 2004-03-28 01:00:00
3. 2004-03-29 02:00:00

This was confusing. By applying the 7th argument to gmmktime() I got it working like it should [at least it seems like that now]!

Even though I litterally RTFM from the start to the end I unfortunately never noticed the 7th argument. I deeply apologize as the whole thing turned out to be bogus. :(

Greetings,
Tico

Sorry, this is a bug in Windows and we can't fix that. PHP 5.1 will have non-OS-dependant date routines so it'll be fixed there.
