Is tick() the same on all timezones?

Lets say somebody in a certain timezone prints tick(), and lets say that at the same time I print tick() in a different time zone. Will tick() be the same for me and the other person? Or no?

os.time() returns how many seconds have elapsed since the UNIX epoch (1 January 1970, 00:00:00), under UTC time.

tick() on the client will return the same but on the local players timezone. I believe tick() on the server get’s the servers timezone, or UTC.
