How to setup a time counter (offline)

[GrandFatherFloppa (TacticalFlopp)]

Trying to create a system where the players can make things, but it will take for example 1 hour, so I dont expect them to stay ingame or so, How can I schedule or something like that.

I’m just spit-balling an idea here.

You can use DateTime.now().UnixTimestamp and save it in a player’s datastore, then when the player rejoins you can do:

local timeSinceLastLoggedIn = DateTime.now().UnixTimestamp - savedTimestamp

-- (where savedTimestamp is the previously saved DateTime.now().UnixTimestamp in datastore)

Try this

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("TimeStore")

local function SaveLastTime(player: Player)
	local key = tostring(player.UserId)
	local timeValue = os.time()
	local attempts = 5
	local delay = 0.5

	for i = 1, attempts do
		local success, errorMessage = pcall(function()
			DataStore:SetAsync(key, timeValue)
		end)

		if success then
			return
		else
			task.wait(delay)
			delay *= 2 
		end
	end
end

local function LoadLastTime(player: Player)
	local key = tostring(player.UserId)
	local attempts = 10
	local delay = 0.1

	for i = 1, attempts do
		local success, data = pcall(function()
			return DataStore:GetAsync(key)
		end)

		if success then
			return data
		else
			task.wait(delay)
			delay = math.min(delay * 2, 1) 
		end
	end
	return nil
end

game:BindToClose(function()
	local players = game.Players:GetPlayers()
	local saveTasks = {}

	for _, player in ipairs(players) do
		table.insert(saveTasks, task.spawn(function()
			SaveLastTime(player)
		end))
	end

	local startTime = os.clock()
	for _, taskObj in ipairs(saveTasks) do
		if os.clock() - startTime < 15 then
			coroutine.resume(taskObj)
		else
			break
		end
	end
end)

game.Players.PlayerAdded:Connect(function(player: Player)
	local lastTime = LoadLastTime(player)

	if lastTime then
		local currentTime = os.time()
		local timeDiff = currentTime - lastTime

		local totalMinutes = math.floor(timeDiff / 60)

		local days = math.floor(timeDiff / 86400)
		local hours = math.floor((timeDiff % 86400) / 3600)
		local minutes = math.floor((timeDiff % 3600) / 60)
		local seconds = math.floor(timeDiff % 60)

		local detailedMessage = string.format(
			"Offline counter: %d, %02d h, %02d m, %02d s",
			days, hours, minutes, seconds
		)

		local minutesMessage = string.format("Player offline: %d m", totalMinutes)

		print(detailedMessage)
		print(minutesMessage) 
	end
end)

game.Players.PlayerRemoving:Connect(SaveLastTime)

This code prints to the console how many minutes the player was offline.
