Most likely asymmetrical paths, yes. To answer your implied
question, it is most /unlikely/ that the USA National Time is 17
milliseconds away from Japan National Time, if that's what you were
thinking. National time differences are likely to be microseconds or
less, I believe.
I believe that the word "less" is appropriate here but might be called
an understatement. I'd guess that the various national time standards
are within nanoseconds or less.
Thanks for the update, Terje and Richard. You must need more digits in
the NTP billboard display, then! <G>
I remember the flying of caesium or other atomic clocks round the world,
and that folks had to invoke relativistic corrections. Were these
better than microseconds as well?
Please excuse me if I leave relativistic corrections to the late
Professor Einstein! It's not something I've ever needed to know!
