Thanks. I'm busy attempting to get my head around mnesia at the moment, 
hence not having a chance to investigate this. This question was sitting 
in the back of my mind distracting me and I thought that there must be a 
standard implementation as it's a common and basic thing to do. So far 
I've found the man page (part of stdlib) for timer which I'll have to 
read later.
