PHP Bug Type: Date/time related
Bug description: strtotime() Reverses Time Zone Offsets
Description:
------------
When using strtotime($timezone), where $timezone is the timezone
abbreviation, it adds negative offsets and subtracts positive offsets to
the time.
If you add a date string, e.g. "April 10, 2009 9:20 AM MDT", the same
problem occurs.
Reproduce code:
---------------
<?php
// It is currently 9:55 pm PDT. Default time zone is PDT.
echo date('g:i a', strtotime('HADT')) . " \n";
echo date('g:i a', strtotime('AKDT')) . " \n";
echo date('g:i a', strtotime('PDT')) . " \n"; // This is the only correct
one.
echo date('g:i a', strtotime('MDT')) . " \n";
echo date('g:i a', strtotime('CDT')) . " \n";
echo date('g:i a', strtotime('EDT')) . " \n";
?>
Expected result:
----------------
7:55 pm
8:55 pm
9:55 pm
10:55 pm
11:55 pm
12:55 am
Actual result:
--------------
11:55 pm
10:55 pm
9:55 pm
8:55 pm
7:55 pm
6:55 pm
