Alliedassault - How do I get 10 min rounds on my spearhead server?

This is the servers cfg file, I tried changing things but I'm not sure what to change to make it 10 min rounds, it keeps sticking with 15 min rounds, which i persoanly prefer...but the twl nazis and other clans keep bitching over the 15 min rounds and I can't seem to change it, what do I need to do?
