PHP and MySQL time not same

[Nirmal Natarajan]

I run PHP and MySQL on the same machine, but both report different times.
I set the timezones by the following methods:

PHP:
date_default_timezone_set('Asia/Kuala_Lumpur');

MySQL:
$db->Execute('SET time_zone = "Asia/Kuala_Lumpur"');

The difference between two times is always exactly 24 seconds. Any idea why this is happening? I thought the times must be same because both reside on the same machine!
