Admin Forum:Dpl cache expiration

I was wondering if anyone knew the default dpl cache expiration time on Wikia. I understood that the extension default is 1 day, but on the Wiki where I'm an admin, warmetal.wikia.com, I've noticed that the dpl cache seems to last longer than 1 day, forcing us to do a null/dummy edit to force the cache to update.
