Bug description: strtotime - crossing daylight savings time
Description:
------------
In the US, Daylight Savings Time ends on October 31, 2004 at 2am where
clocks are then reset back to 1am. I am in the Eastern time zone. If I
run the following script where I'm adding 1 hour, 2 hours, and 3 hours to
the date 2004-10-31, I'm getting different results from including EDT in
the date or not, when I thought that strtotime() defaults to the local
timezone.
Reproduce code:
---------------
<?php
echo date('Y-m-d H:i:s', strtotime('2004-10-31 EDT +1 hour'))."\n";
echo date('Y-m-d H:i:s', strtotime('2004-10-31 EDT +2 hours'))."\n";
echo date('Y-m-d H:i:s', strtotime('2004-10-31 EDT +3 hours'))."\n";
echo "\n";
echo date('Y-m-d H:i:s', strtotime('2004-10-31 +1 hour'))."\n";
echo date('Y-m-d H:i:s', strtotime('2004-10-31 +2 hours'))."\n";
echo date('Y-m-d H:i:s', strtotime('2004-10-31 +3 hours'))."\n";
?>
Expected result:
----------------
2004-10-31 01:00:00
2004-10-31 01:00:00
2004-10-31 02:00:00
2004-10-31 01:00:00
2004-10-31 01:00:00
2004-10-31 02:00:00
Actual result:
--------------
2004-10-31 01:00:00
2004-10-31 01:00:00
2004-10-31 02:00:00
2004-10-31 01:00:00
2004-10-31 02:00:00
2004-10-31 03:00:00
