Message
I needed this for something else and since it seems to be fairly useful (if rather trivial) I've posted it :)

What it does is populate the plugin's variable space with the time that it last received a new entity message. Discworld MUD uses these to track hitpoints &c.. and from this information I can add a field to my InfoBar with how old the data is.

You can replace the time.clock() call with a time.time() call if that suits your purposes better.

(time.time() returns the unix epoch tick while time.clock() returns the number of seconds since the first call to time.clock() as a float with millisecond precision)

Also, this should be fairly easy to implement in Lua for portability, but not something I've done yet.
