A hud timer

Hey guys, i’ve been starting lua, and making a gamemode, its called CS, (CatastrophicSurvival) and I am in need of a timer, but I dont know how to do that, could someone help me with that? My steam name is stany10, if you want to add me.

But, I mean a hud-like, that shows the time untill something happens.
So it shows the numbers on your hud.

use this with a draw.Text function : **[String.ToMinutesSeconds


And feed it with your remaining time!
