Using it on the client should return your time. Look through the formatting in the article and test In Studio (and possibly in a live game) if it works. You want to convert something like GMT + 1 = 13:00 → GMT + 3 = 15:00?
You’d have to use RemoteEvents for client-server communication, as it is required to do this. What exactly do you want to do if that post didn’t fix it?
I think i can also do it on the Server, when i print os.date, it will print the Date with the Time correctly but i want to just show the Date with the German Timezone and what do you mean, do you mean what i want to archivie?
