I've not been about for a while, but I know there are some electronic geniuses about on here (or at least people who have more of a clue than me!), so figured I'd ask here.

I know somebody looking for a timing system for races, but the quotes so far have been a fair bit more than what they'd hoped for. I reckon a basic system could be done for a far more reasonable sum, but I'm having trouble trying to find anything capable of supplying an accurate time.
The RTC chips I've found so far only seem to be able to supply the time to the nearest second, when ideally I'd need at least 0.1second or even 0.01second accuracy.

Like all things, I'm sure there is a proper name for what I'm looking for, but numerous google searches havn't tunred up anything useful, so does anybody have any suggestions?
