Description:
------------
30th, march has only 23 hours. 2 o'clock is missing :)

using:
- php 4.3.3 with default config
- Windows XP with SP1 and all important updates found on windowsupdate.microsoft.com

Reproduce code:
---------------
// time is 30th, march 2003
$time = mktime( 0,0,0, 3, 30, 2003 );
echo date( 'm/d/Y (H:i:s)', $time );
echo "<br>\n";

// show gap
for( $i = 0; $i < 2; $i++ ) {
	$time += 60*60;
	echo date( 'm/d/Y (H:i:s)', $time );
	echo "<br>\n";
}

echo "<hr>\n";

// reset to 30th, March 2003 (01:59:59)
$time = mktime( 1,59,59, 3, 30, 2003 );
echo date( 'm/d/Y (H:i:s)', $time );
echo "<br>\n";

// show gap
$time++;
echo date( 'm/d/Y (H:i:s)', $time );
echo "<br>\n";

Expected result:
----------------
03/30/2003 (00:00:00)<br>
03/30/2003 (01:00:00)<br>
03/30/2003 (02:00:00)<br>
<hr>
03/30/2003 (01:59:59)<br>
03/30/2003 (02:00:00)<br>

Actual result:
--------------
03/30/2003 (00:00:00)<br>
03/30/2003 (01:00:00)<br>
03/30/2003 (03:00:00)<br>
<hr>
03/30/2003 (01:59:59)<br>
03/30/2003 (03:00:00)<br>

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.

*sigh*
