Why isn't this DataStore script working and am I doing it correctly?

I want to save the time in the game and this script is not working. I have turned on API Services. Code:

local ds = game:GetService("DataStoreService")
local data = ds:GetDataStore("ClockTime")

game.Players.PlayerAdded:Connect(function(p)
	local success, err = pcall(function()
		game.Lighting.ClockTime = data:GetAsync(p.UserId)
	end)
	if success then
		print("yay")
	end
	if err then
		print("err: "..err)
	end
end)

game.Players.PlayerRemoving:Connect(function(p)
	local success, err = pcall(function()
		data:SetAsync(p.UserId, game.Lighting.ClockTime)
	end)
	if success then
		print("yay")
	end
	if err then
		print("err: "..err)
	end
end)

When I am doing this in game, it just sets it to the time in the game and not the DataStore save.

Thanks, b_mni.
