Help Tick

Many of the game actions (including combat, most autonomous monster 
actions, hp/mana/move regeneration, weather, and area resetting) are based
upon interval timers.  Of these timers, the hp/mana/move regeneration timer
is popularly called the 'tick'.  Ticks on this mud average around 30 
seconds of real time. This represents about an hour of game time.

Area resetting depends on the area, but for most areas is somewhere between
5 and 10 minutes each reset. Items in the room will repop regardless of 
whether or not a player is in the room.  Players in an area no longer have
an impact on the time an area takes to repop.
