Tick timer
Estimates the time left until the next game tick in the MUSHclient status area. (see 'help tick')
Down at the very bottom, underneath your input bar. It says "Time to tick:" and then a number of seconds remaining.
Ticks aren't guaranteed to happen after exactly 30 seconds, and the timer isn't guaranteed to be ultra precise in all cases, so the countdown timer is set to a resolution of 2 seconds for psychological reasons. It is easier for the player to cope with ticks being off by a second or so if they expect the timer to only update coarsely.
