Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
I believe the rounds are 30 minutes. Some maps like problematic need 30 minute long rounds. But after 30 minutes, people want to switch to the next map. 95% of the maps do not have a flag that ends the round. You must have joined the server with 2 minutes left
