Description:
------------
I set date.timezone in php.ini to 'Asia/Bangkok', and all calling to the function date() is correct along the code running, except once I call it in my session_handler->write() which UTC is always returned. I can correct it by calling date_default_timezone_set in the method then the returned date is correct.

By the way, I found my Apache will crash many times during the call to function date().

Actually, my script works well for 2 years with any of PHP 4.x.x

Reproduce code:
---------------
- Setting the option date.timezone in php.ini to 'Asia/Bangkok'
- Call date() anywhere you want, the return is correct.
- Call date() in $a_session_handler->write(), the return is UTC.
- Add date_default_timezone_set() in $a_session_handler->write() before calling date(), the return is correct.

Expected result:
----------------
date time in the time zone set

Actual result:
--------------
UTC time
