If you are working "real" EME where you, and not a computer plus lookup table,
are coping the signals, none of these precise timing issues exist.

I must admit to being rather puzzled at the sub microsecond timing requirement
as I use ntp to set the W7 clock in my computer and have not had any issues.
In fact less than one second is OK for the usual two minute periods that are
required to allow for the Faraday rotation. Although I use a GPSDO for a
frequency reference I find JT software reasonably tolerant of frequency. As I
may be missing something I would welcome observations on how important the
period timing requirement is, you never know I might get more contacts.

For the group. This ham is trying to work EME. Earth-Moon-Earth propagation
path. Aka, "moonbounce."
He is trying to time synchronize a system, where the other station he is
communicating
with can be any other place on the Earth that can also see the Moon.
So the system time sync is for a little bit tougher case than a local area
network.
