There should be very little reason to use Dimension 4, with step updates 
at fixed intervals.  The full implementation of ntpd is available for 
all the Windows NT family, i.e. everything after Windows 95, and 
versions or w32time that can be configured to implement the older 
version of NTP  have been supplied with Windows since at least Windows XP.

The standard ntpd always works by managing clock frequency, so there are 
no abrupt time steps unless something has gone sufficiently wrong to 
result in a step of at least 200ms.  w32time can be configured to work 
that way, although generally installing the standard (reference) version 
of ntpd is preferred.  (ntpd can be configured to almost never step the 
time.)

Although Windows is not a good platform for time keeping, both these 
approaches ought to produce times accurate to about 20ms, and only 
slowly changing with time.  In some circumstances, Linux can produce 
several orders of magnitude better results.

I had it set for updates every 1 sec as I didn’t think that was a problem.  I now have it set for 30 Mins and probably and hour would not hurt anything as every 15 secs it does about .049 correction on my computer.  I don’t think it is abnormal for the Rates on WSJT-10 to jump out of range when a time update is done to the computer.  Something you cant see on WSJT-X or JTDX.  Thanks to all that wrote with suggestions, all of them good.  73 Mike K4PI
