Since the server is normally always up and there's no down/restart, what is our fake daily restart time? I figure this must be accounted for somehow, at least for the purpose of respawning rares.
Currently there are no rare spawns tied to a server restart. Even in the case of a restart the timers would be saved while the server is down. Its possible on other servers with 20-30 minutes of downtime, if an item was due to spawn during the downtime, it would spawn in the first timer cycle after the reboot, resulting in a "Server Up" spawn. However everything on Renaissance is on a timer, unlinked to any server restart.
