Hello!

I just need some help here. I'm making a timed door (a door that opens at a exact time, example when time hits 20 mins left, the door will open automatic.) I have no idea how to make it, but i was hoping one of you guys might know how to. I was on a other webpage someone told me about, but absolutely everything was on polish, and i don't know any polish at all. If so, can someone make me a tutorial how to? With scripts if possible.

Cheers!
