Bug description:Some relative date/time format returns incorrect result at the
end of DST
Description:
------------
Relative date/time format '+[number]sec', '+[number]min', '+[number]hour'
returns incorrect time when the current time is in daylight saving time and
the result of calculation is non-daylight saving time.
For example, daylight saving time of this year in the USA was started at
2010-03-14 02:00:00, and finished at 2010-11-07 02:00:00. However,
'2010-11-07 01:59:59 +1sec' advance to 3601 sec after.
Test script:
---------------
<?php
date_default_timezone_set('America/Los_Angeles');
echo date("c", strtotime("2010-03-14 01:59:59")) . PHP_EOL;
echo date("c", strtotime("2010-03-14 01:59:59 +1sec")) . PHP_EOL;
echo date("c", strtotime("2010-11-07 01:59:59")) . PHP_EOL;
echo date("c", strtotime("2010-11-07 01:59:59 +1sec")) . PHP_EOL;
Expected result:
----------------
2010-03-14T01:59:59-08:00
2010-03-14T03:00:00-07:00
2010-11-07T01:59:59-07:00
2010-11-07T01:00:00-08:00
Actual result:
--------------
2010-03-14T01:59:59-08:00
2010-03-14T03:00:00-07:00
2010-11-07T01:59:59-07:00
2010-11-07T02:00:00-08:00
