Windows 10 uses the Network Time Protocol. (By default it uses MSFT’s server, but to change it you don’t click on the clock like some instructions say, you click on the Windows icon -> gear icon/Settings -> Time & Language -> Date & time (scroll down) -> Add clocks for different time zones -> Internet Time tab -> Change settings. The default is time.windows.com but time.nist.gov is on the drop-down list and you can type in another one if you know of it. (Hiding the NTP server under clocks for different time zones doesn’t make any sense to me, they’re completely independent things.)
So do you still need Dimension 4 or anything like it on Windows 10 for any ham radio applications?
The following command was found on the page https://docs.microsoft.com/en-us/windows-server/networking/windows-time-service/support-boundary C:\Users\aki>w32tm /query /status Leap Indicator: 0(no warning) Stratum: 2 (secondary reference - syncd by (S)NTP) Precision: -23 (119.209ns per tick) Root Delay: 0.0596572s Root Dispersion: 7.7760869s ReferenceId: 0x84A36001 (source IP: 132.163.96.1) Last Successful Sync Time: 3/22/2021 4:58:06 PM Source: time.nist.gov,0x9 Poll Interval: 10 (1024s)
April 12, 2021 at 8:45 am #119948Dimension 4 uses SNTP (Simple NTP) instead of NTP (Network Time Protocol). (See <https://www.orolia.com/sites/default/files/document-files/Differences_Between_NTP_and_SNTP_v1-02-13-19.pdf>. SNTP only checks one server and uses simpler algorithms than NTP. For example, SNTP makes the PC’s time setting simply jump to the correct value.) It’s certainly easier to find Dimension 4 on the Windows Start menu than to find the Windows setting for the NTP server under the control panel for changing the time zone, and Dimension 4 has a far longer list of time servers built into it than the Windows 10 setting does so that you can find one closer to you. (Although I guess the network routing affects this.) So I installed Dimention 4 on my shack’s Windows 10 machine.
April 12, 2021 at 9:09 am #120172I have an NTP server built into a raspberry pi with a GPS dongle and I have all my shack computers syncing to it. Thus I (nominally) am connected to a Stratum 1 server. Not that I need microsecond accuracy, but it was fun to set up.
