How save timestamp according to Asia timezone

Hi
I receive timestamp base of UTC and save it into database
Now i need report all data example between 2:30 to 14:43
And i am Tehran with GMT +3:50
Can i save timestamp base of Asia/Tehran timezone or i can only get their base of my favorite timezone?
Can i set timezone to Asia/Tehran on mysql when i use SELECT command?
Thanks

Hi, not sure is that what are you asking, but you can use mysql date_add and date_sub functions.

In CI4 there is options for timezone setting on
public $appTimezone = 'America/Chicago';
This may help,
In CI3 in application/config.php
date_default_timezone_set('America/Chicago');
