WP Does Not Display Correct Date

I am currently running a website using WP2.8.4 at https://www.smkmethodistsibu.org. The php echo date returned the wrong date although I set the UTC option to +8 hours in the admin area. When I tested php echo date(‘e’) on my header.php, it came up as “America/New_york”. Problem is I live in Asia. How do I resolve this problem? My readers are all based in Asia and I do not want them to see the wrong date on my site.

Any help will be much appreciated. Thanks.
