not sync time #1

Closed panshengjie closed 2 years ago

panshengjie commented 3 years ago

hello!

when I first run pps-clinet , It prints 2021-05-28 12:15:12.000000 20 jitter: 0 freqOffset: 0.000000 avgCorrection: 0.000000 clamp: 32768*

some time past, it goes 2021-05-28 15:13:50.000000 10738 jitter: 0 freqOffset: 0.000000 avgCorrection: 0.000000 clamp: 1

so I thought time synchonized. But then I changed sys time with wrong time(for test) , however it did't detect/correct it, something is wrong

I've tried restart/reboot/reinstall, change time in milliseconds, and some . Nothing changes, still print 2021-05-28 17:00:31.000000 18582 jitter: 0 freqOffset: 0.000000 avgCorrection: 0.000000 clamp: 1

it seems a data/cache is saved somewhere in disk (because num keep counting on), and I can't find it, even pps-client-remove -a

This is exactly what happens when no PPS signal is present. This is not a problem with PPS-Client. It's a problem with electrical connection or connection software.
