This has undoubtedly been done before, but here's my rendition of a script to lock and unlock doors in an area based on the time of day. It works from the area heartbeat by checking for "hour_locked" and "hour_unlocked" local integer variables on the doors in the area, then locking and/or unlocking each door at its appropriate hour. I used a method (similar to the walk waypoint controller used in the x0_i0_walkway include) of setting up a controller waypoint that has a list of door objects with the appropriate variables set. When added to the area heartbeat, the CheckDoorLocks routine will run through that list of doors once per hour to check if the state needs to be changed. It also closes any of the doors that need to be locked. (I could probably also check the lock state using GetLocked before calling SetLocked, but I'm not sure that would be much more optimal.)

// ww_inc_doorlock
/*
  The following routines provide functionality for handling
  door locking and unlocking based on the hour of the day.
  The time range is defined by storing local integers on
  each door: "hour_locked"/"hour_unlocked", with the value
  between 1 and 24 inclusive. The door must be set lockable.
  The CheckDoorLocks routine should then be called from the
  area's heartbeat script.
