Every object has a timestamp, which includes the time last used, the time last modified, the time the object was created, and the number of times that that object has been used by a player. They are shown by using EXAMINE. 'Usage' is defined as follows: Players-when they are connected, Rooms-when entered or 'look'd at, Exits-when invoked (by a 'go' command) or 'look'd at, Things-when 'look'd at or 'take'n/'drop'd, Programs-when run by a player. Examining an object does not count as looking at them.
