How do you make a time zone in your roblox game? for school?

Im making a high school game and before i sort out the classes i need to make a time zone so i can make it so you have to be at a certain place at a certain time. But i dont know how. Anyone got a script i can use :)

You just need to decide what you want your interval(s) to be. And then after each period, cause something to happen. (You could print out a message to everyone saying that the next class has started or whatever)

Example:

while wait(30) do
	print("30 seconds have passed...")
	--Do something (Teleport everyone somewhere, idk..)
end
