Map changing

[CubicVirtuoso]

I just kinda have a general question about source DS. This seems to happen on both my Linux and Windows servers. I have a map cycle and such installed on my server however the server will only count time unless there is someone in the game. For example... I start the server on dm_lockdown and no one will join for about 4 hours (lets just say) then someone joins and the mp_timelimit starts to count and after 20 mins (my map rotation limit) that map changes. How can I make the map change even if there is no people in the server?

Thanks.
