It depends on how you define accuracy. With a wired system is is very easy
(ie, cheap) to make a system with much better than 0.001 resolution (even if
you only show 0.001) that will be accurate when comparing cars timed at
different times of the day on the same system.
It becomes slightly more difficult if you need to compare elapsed times
taken on systems that cannot be synchronized. Then you need to know that
the clocks are running at the same speed to within 0.001/(elapsed time).
