Your server's global time configuration cannot be changed, however, you can set the timezone for your website using hPanel or PHP function:
Setting up timezone via hPanel
Open Hosting → Manage → PHP Configuration page. There, open the PHP options tab and edit the date.timezone value:
If you are not sure which time zone to insert, check the Time Zone Map.
Save the changes at the bottom of the page, and the timezone will be updated successfully 🚀
Setting up timezone via PHP function
As an alternative to the previous option, you can set the timezone using date_default_timezone_set PHP function. Just check the List of Supported Timezones, find the one which you need, and insert the following code to your website (in most cases, to index.php):
<?php
date_default_timezone_set("Asia/Bangkok");
echo date_default_timezone_get();
?>
NOTES:
Don't forget to change "Asia/Bangkok" to the desired timezone
This change will affect only files. You can also apply a different time zone for the database (1 session)
