Change System time to insert data in mariaDB

Hi, I am ruining HassOS 4.11 in Raspberry Pi 4 4GB.
In mariaDB, homeassistant database on states table, I do notice the system capturing system time instead of local time.

In config.yaml file i did the following

    name: Home
    elevation: 66
    unit_system: metric
    time_zone: Asia/Kuala_Lumpur

But the system time doesn’t change. I did tryout most of the suggestion in community but doesn’t help.

Please do share if anyone has the solution.
