Round Time CTF?

Hi guys someone please can tell me how to change the Round time in Capture the Flag mode??

i looked over everything but cant seem to find it!

Would appreciate some help.

I haven't tested it, but if you look under Basic Game State Manager, there is a space called RoundDuration. The default is set at 120. You can try that, but I'm not sure if there are other places you need to change things.
