GPS recievers would seem to be accurate time sources - they have to solve
for time to determine position, and that time has to be quite accurate.
Because they are (mostly) mobile, they would seem to be ideal time sources
for TSD rallyists, where scores are based on hundredths of a minute.
At least one rallyist tested GPS receievers and discovered that they were
not reliable time sources. The time displayed on the front and reported
to the serial connections differed by several seconds after only a
relatively short time. If you are interested, I suggest that you check the
archives of the rally-l list at http://scifi.squawk.com/rally-l.archives.
I think the message was posted in the last month or two. Apparrently,
some contain a free-running clock which is not synched with calculated
time.
Of course my password is the same as my pet's name.
My macaw's name is Q47pY!3, and I change it every 90 days.
