Hi everyone!

I was making a timer for my game, and realized that when it started, it usually started 3-20 seconds ahead. It didn't get stuck at 0 for a bit then changed to the right time, it just started at that time immediately.

Here is the script that runs the timer:

local isRunning = false
local rs = game:GetService("RunService")

script.Parent.Start.Event:Connect(function() -- this event is running
	if isRunning == false then
		isRunning = true
		local timer = script.Parent
		if isRunning == true then
			if isRunning == false then print("yes") return end
			rs.Stepped:Connect(function(sec, _)
				wait()
				local truemili = math.floor(sec * 100)/100 - math.floor(sec)
				local miliseconds = tonumber(string.sub(truemili, 3, 4))
				if miliseconds == nil then miliseconds = 0 end
				local minutes = math.floor(sec / 60)
				local seconds = math.floor(sec)
				if seconds == 60 then
					seconds = 0
				elseif seconds > 60 then
					seconds = seconds - (60*minutes)
				end
				if miliseconds < 10 then
					miliseconds = "0" .. tostring(miliseconds)
				end
				if seconds < 10 then
					seconds = "0" .. tostring(seconds)
				end
				script.Parent.Text = minutes .. ":" .. seconds .. "." .. miliseconds
				script.Parent.Time.Value = minutes .. ":" .. seconds .. "." .. miliseconds
			end)
		end
	end
end)

script.Parent.Stop.OnClientEvent:Connect(function()
	isRunning = false
	script.Parent.Text = "00:00.00"
	script.Parent.Time.Value = "00:00.00"
end)

If anyone could please tell me whats wrong here, id really appreciate it :)
