Force time for discovery runs RC Poller

Hi all

With the Dispatcher service, I know it is possible to set the interval at which stuff is polled and discovered, but is it possible to set the time when a discovery should run? I have my discovery set to once in 24 hours, because of a largley static environment. So I would like this to happen at night. Currently it seems it is running in the middle of the day. Any way to change this? (I know I can revert to cron-based polling, but I want to rather do it “the right way”)
