Need a way to detect when 5 minutes have passed while keeping it synced across all servers

[Textible (Text)]

Currently, I have this code so far.

local rotationMinutes = 5 * 60

--math.ceil(os.time() / rotationMinutes)
-- seed changes every 5 minutes

I need a way when a new server is created, that the timer will be until the next seed change. I don’t want to use any long modules or datastores for this. I tried looking up how I would be able to sync this code efficiently, but found no results.

I made a way that uses data stores, but I figured there should be a way with some math to calculate each item and the time until the next item without datastores or https service.

I am using this for a shop that changes every 5 minutes, preferably without any long functions and just some math. If you are able to help that would be appreciated!

TLDR: I need some math to calculate how long until the next seed change

What’s the problem with your current approach of clamping the os.time? I see you commented it out, but that’s going to be how you’d want to do it.

yeah, server os.time is the same for all servers, the code would be as simple as getting the time until the next 5 minute mark, which is simple, since the value could never be higher than 5.

use os.difftime os | Documentation - Roblox Creator Hub for it.

I will try that, didn’t know that function existed.

The comment is the current code, there wasn’t a way to check how long from that code.

I tried using it but it returns -1, I found another way. Thanks for your help though

local rotationMinutes = 5 * 60

while task.wait(1) do
	local nextTime = math.ceil(os.time() / rotationMinutes)
	print(math.round((math.ceil(os.time() / rotationMinutes) - os.time() / rotationMinutes) * rotationMinutes))
end
