as longtime time-lord, I echo Bob’s note to use the pool servers.

Also, if your product allows, enter more than one server.
0.pool.ntp.org
1.pool.ntp.org

Cuts down  vulnerability  to falsetickers.

For a true WIN10 system:
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org 3.pool.ntp.org"

Yes, use us.pool.ntp.org .  I stopped trying to use time.windows.com and time.nist.gov a long long time ago.

A couple questions about syncing time on pc’s… I had been setting windows and my webcams to sync with time.nist.gov, but recently that has been failing on several different machines… both on a webcam that I think runs some kind of cut down linux, and on win7 and win10 boxes.  Time.windows.com seems to work on the ones that time.nist.gov fails on, but I’m not sure how accurate it is.  I have 2 machines that run wsjt-x when nothing else is happening and 2 machines that run cw skimmer server and rtty skimmer server 24/7, plus the n1mm+ logging network that needs to sync to something for multi-op contests, plus 2 webcams that time stamp photos that I would like to be at least reasonably close.

 

Questions…

1.       Does anyone know if there is a difference between time.windows.com and time.nist.gov that would make some machines fail to sync on one but work on the other??

2.       I have a server, win 2012r2 that syncs to time.windows.com, would I be better off setting all the lan machines to sync off it rather than doing their own sync over the internet??

3.       Is there a better source than time.windows.com or time.nist.gov that works reliably with windoze??
