PS 1.7 time reading place

[Zudriuz]

Does anyone know where the time used by PS 1.7 is read from? Because as far as I understand, PS 1.6 reads the time from one place, and PS 1.7 from another place, maybe someone has analyzed the PS 1.7 time reading? As far as I understand, it is indirectly taken from the PHP.ini file for system use, but taken from somewhere deeper, maybe from the PHP server itself, or the MySQL server. Because maybe, knowing where it comes from, it would be possible to somehow cheat in the code at that time? It would be possible to somehow add the required difference.
