[request] How to change buff duration

I've used the search but couldn't find a topic about this

I want to change the duration of certain buffs like "Bush" and that kind.
I've tried changing them in DB (dbo.Skills -> KeepTime) but it doesn't shows in game.
I want to make "normal" buffs to stay for 15-20 mins, instead of 5 mins.
Do I have to edit something else besides that db field?

you need to change it in the sdata as well.
please stop posting in the wrong section.
