Is there a way to clear time played in GZDoom?

[Nevander]

Let's say you have an intro map that comes before MAP01. The intro is not a real map but it still counts your total time for that continous run. Is there some way or some trick to force the time to start over? Maybe some kind of stats clear with ACS?

I'm thinking there's a way to mess with this using ZScript, in GZDoom, but I have't screwed with it yet.  If you can't though, speedrunners will likely just roll with it...
