Need to set fixed time zone permanently in pmm server

How to set permanent time zone in the pmm server. For example if I am from IST but it should always be a PST time zone while accessing any dash board. Is it possible to set time zone permanently in the PMM server?
Even for QAN also, we need a fixed time zone irrespective of the country time zones.

After you log in to PMM, click the gear icon in the bottom left and go to ‘Preferences’. Here you can change the global timezone.

Thanks @matthewb for the help.
