Would this not also be dependant on one`s computer. My previous ham use
computer when I started with JT65 it would not function until I added a time
sync program and I had to set this program to adjust the time each minute to
provide decent decodes. My new machine is much more stable and it is now set
for every 5 minute update. Why hesitate to install something that helps you and
those your trying to communicate with.

This strikes me as perhaps dated with respect to Windows 10.
My Win 10 Pro box here (1809, 17763.134) runs the default Windows Time Service,
always has - configured to 'set time automatically'. Every now and again I'll
look at
time.is and it'll say I'm within 15mS. I just powered-up a Windows 10 Home
notebook
that has been powered-down a while; it was off 2 minutes, but I did a manual
'Internet Time Sync' and it seems to tracking well (I suspect it might have
been
skewing back on-time and I kicked the process along).
[I did select time.nist.gov as my time server on one system, but
time.windows.com
seems functionally as good]
Note that Windows 10 (version 1607 or later) documentation says:
"Time synchronization in Windows 10 and Windows Server 2016 has been
substantially improved. Under reasonable operating conditions, systems can be
configured to maintain 1ms (millisecond) accuracy or better (with respect to
UTC)."
but the *default* configuration isn't intended to provide that level of
accuracy:
"While we support accuracy up to 1ms on Windows 10 or Windows Server 2016, the
majority of customers do not require highly accurate time."
But they explain how to configure your Win 10 system for high accuracy:
https://docs.microsoft.com/en-us/windows-server/networking/windows-time-service/configuring-systems-for-high-accuracy?tabs=MinPollInterval
I'm going to give the 'high-accuracy' changes a try; I might change time server
to time.windows.com to avoid hitting NIST too often.
Odds are that you're better-off using the built-in Windows Time Service than
a third-party service on Windows 10 version 1607 or later. Fewer moving parts
is always better.
