Timer on HUD? Noob LUA question.

Hey,

because there is no public “climb” gamemode for garrysmod, I want to try to make my own.

The thing I need now is a timer that resets on spawn and print the time on the hud, like a stopwatch.

I already googled but didnt find anything that helps me.

I guess its pretty easy for someone that knows lua.

thanks.

Sorry for my bad english.
