What is the sync time tolerance? For example, following the directions here
https://www.windowscentral.com/how-manage-time-servers-windows-10
https://www.thewindowsclub.com/change-internet-time-update-interval-windows

or using any number of products such as D4, you can be within 0.01, +- 0.01 s...

Windows defaults to syncing time weekly, but I have mine set at hourly.
At any time, I can go here
https://time.is/

to see how far off I am...is this close enough for FT8? One note I saw said "But if you can get your clock within, say, a half a second, you'll be fine for FT8 and FT4." and this method certainly exceeds that spec.

I'm not an FT8 kinda guy, but I ran across this
