GPS measured elapsed distance

I would like to share programming experience with those who have worked on public domain software for GPS measurement of elapsed distance.
There are two basic approaches: one using rate x time and the other adding the distances between frequently obtained coordinates along a track. It is not a trivial problem due to position variability when the GPS is not in motion, limitations of the (PDA) programming languages regarding date-time data, and difficulties obtaining a regular "time tick" that is synchronized with the transmission of the GPS motion data.
