how do I make every servers time the same using a time from a real life region like asia?

So for example I want every single server to be the same time as the united states how would i script that is there like a region variable or something?

You can use os.time to calculate time in different places.

os.time returns the seconds elapsed since UNIX epoch and returns it in utc time, aka greenwich mean time (GMT)

For example:

Japan's timezone is at utc +9, therefore Japan's time is 9 hours more than the time in utc.

print( os.time() + (9*3600) )
