as a TSD rallier I would suggest:

1 - time format to be in HH:MM.MM (division and addition of time is much eaiser when working with decimal minutes)

2- while GPS time or NTP time is accurate, it is not rallye time. you'll want to make an easy quick interface to modify the time. the rally master will display their clock for everyone to sync with.

3 - BIG numbers on the display..

when 2.0 hits the net with the talked about visual API it may be alot eaiser to put all this together.. you could also turn this out rather quickly with perl.
