I imagine they didn't want to standardize this and just leave it up to the DM to decide if it was important to establish.Something else: Guidance on the average time it takes to search dungeon chambers based on how they're stocked would be helpful. We know how long it takes to travel down a 30 ft. corridor based on travel speed, but how long does it take to explore a 30 x 40 ft. chamber based on its purpose, state and contents?
For my part, I generally say 10 minutes for a given dungeon exploration task in a 1,000 square foot area - keep watch, loot, search for secret doors, search for traps, pick a lock, etc. This also keeps it in line with many rituals or spell durations. Wandering monster checks are done at 10-minute or 1-hour intervals. Anyone doing something other than keeping watch during that 10 minutes is automatically surprised if a stealthy monster is indicated (but not all monsters are the stealthy sort).
