Using WSJT-X, 1.8.0-rc2 version, I just watch the decoded signals on the
Band Activity window and the DT value being displayed. If they are less
than 1.0 second either + or - value, the computer time is satisfactory.
If the DT value is greater than +/-1.0 second, I use internet time to
update the computer. You may have to choose one of the three choices to
attain the best resolve for your location. Most of the time I find
signals are ~0.5 +/- seconds. Everything you need is in Windows for
time synchronization, thus otherwise, it is no big deal.
