game.Players.PlayerAdded:connect(function(Plr)
	local stats = Instance.new("IntValue")
	stats.Parent = Plr
	stats.Name = "leaderstats"
	
	local time1 = Instance.new("IntValue")
	time1.Parent = stats
	time1.Name = "Seconds"
	time1.Value = 0
	
	while true do
		time1.Value = time1.Value + 1
		wait(1)
	end
end)
