Milliseconds?  So why are we talking about HP counters and PicTic and
so on.  A basic low end Linux system that is controlled by NTP and a
GPS receiver is maybe about 100X better than your requirements.
(I figure you are looking for about 1000 parts per million, NTP is way
better then that if you have a local GPS)
