Unless I missed it no one has mentioned " Karen's Time Sync " From the
time JT44 was introducedĀ I used Dimension 4 , as computers became
faster and Op systems changed . D4 started giving me intermittent
problems ! Two weeks ago I started usingĀ Karen's Time Sync with no
plans to change .

Yikes! +/-30 secs and you might not even be transmitting when the other station
is listening.
It's pretty well accepted that <1s is minimum accuracy for good performance. On
EME you're looking for dT around 2.5 secs to help identify valid signals. If
you're not within 0.3s, I'd be looking for a better solution.
Dimension 4 worked great on my XP machine. When I upgraded last year to a much
faster Win 7, per recommendation from EME guru W7GJ's site, I installed
Meinberg which has been trouble free. Since K6QXY's computer for JT isn't
internet connected, I got a USB puck GPS receiver and NMEATime from
VisualGPS.net for Bob, and it's been an excellent solution. Software plus
receiver around $50. I expected we'd have to put the puck outdoors, but it
locked just fine laying on the computer desk.
That's been my experience!

For what it's worth, plus or minus 30 seconds isn't all that big a deal.
