Description:
------------
date() function works incorrect :-(

Reproduce code:
---------------
# check line 179-180, it should add a minute every step

for ($i=0,$d=1224964800;$d<=1225051200;$d+=60,++$i)
	echo "<br>$i -> ".date('Y-m-d H:i:s',$d);


Expected result:
----------------
179 -> 2008-10-26 02:59:00

181 -> 2008-10-26 03:01:00
182 -> 2008-10-26 03:02:00

Actual result:
--------------
179 -> 2008-10-26 02:59:00
180 -> 2008-10-26 02:00:00
181 -> 2008-10-26 02:01:00

We are happy to tell you that you just discovered Daylight Savings
Time. For more information see:
http://webexhibits.org/daylightsaving/b.html
Instead of using mktime/date consider using gmmktime and gmdate which do
not suffer from DST.
