How to automatically synchronize the time and date for several logic machines?

[admin]

Have you restarted the Windows time service after changing the parameter? From the log it looks like the time is still rejected. Sync frequency is not a fixed time, check this: https://notes.networklessons.com/ntp-poll-interval

Dear Admin
Yes, I restarted the Windows for 2 times after changing the parameter.
Test run again today, still the same issue, No time adjustment happens automatically.
Thanks for your efforts.

Changing LocalClockDispersion to 0 works for me.

Test script:

Code:

res = io.readproc('ntpd -ddd -nq -p 192.168.0.2 2>&1')
log(res)

Time is updated:

Code:

ntpd: sending query to 192.168.0.2
ntpd: reply from 192.168.0.2: offset:+106.316103 delay:0.000457 status:0x1c strat:1 refid:0x4c434f4c rootdelay:0.000000 reach:0x01
ntpd: no valid datapoints, no peer selected
ntpd: poll:1s sockets:0 interval:1s
ntpd: sending query to 192.168.0.2
ntpd: reply from 192.168.0.2: offset:+106.316103 delay:0.000573 status:0x1c strat:1 refid:0x4c434f4c rootdelay:0.000000 reach:0x03
ntpd: current time is 2023-06-26 13:08:02.956806
ntpd: setting time to 2023-06-26 13:09:49.272909 (offset +106.316103s)

Since this is clearly not an LM issue there's nothing else that we can help with.

Dear admin,

Yes!!! You are right.
I replaced the old PC with SurfacePro, and set all parameters which mentioned above.
Now, LM5 can automatically synchronize the time with SurfacePro.
Excellent!
Thanks a lot!
