wfm with my local timezone (Germany, GMT+1) but I could reproduce it,
after I've changed the timzone to GMT+0 (Dublin, Edinburgh, Lissabon,
London)

Description:
------------
This bug seems to have different affect on Windows and Linux.
Windows
------
System has to be running GMT and Automatically adjust clock for
daylight savings time checked.
You'll notice that the 27th appears twice. The second occurence of the
27th is Sat Mar 27 23:00:00 2004.
------
Redhat 9.0
------
The timestamp for linux on the 28th is Sun Mar 28 02:00:00 2004
/etc/sysconfig/clock
ZONE="Europe/London"
UTC=true
ARC=false
------
So Windows lost an hour and linux gained 2 hours.

Changing the time to
02:01:01 seems to correct this issue and the windows machine stops
eating an hour and not setting tm_idst to 1 and i have no idea whats
going on with the linux machine.
Reproduce code:
---------------
<?php
for ($i = 26; $i <= 29; $i++)
{
$datestamp = gmmktime(0, 0, 0, 3, $i, 2004);
$day = gmdate('j', $datestamp);
echo "$datestamp - $day\n\n";
}
?>
Expected result:
----------------
1080259200 - 26
1080345600 - 27
1080432000 - 28
1080518400 - 29
Actual result:
--------------
Windows

1080259200 - 26
1080345600 - 27
