rPi time drift

Anybody with more experience with this devices have any idea why their real time clocks would start to drift? Suddenly I'm getting a bunch of messages in the log like

    Jul 17, 2017, 6:32:46 PM
    piBeacon rPi 3 do a time sync MAC --> RPI, time off by: 10.1[secs]
    piBeacon rPi 2 do a time sync MAC --> RPI, time off by: 7.4[secs]
    Indigo Cocoa client authenticated (192.168.10.28)

    piBeacon rPi 2 do a time sync MAC --> RPI, time off by: 16.2[secs]

    Jul 17, 2017, 6:34:16 PM
    piBeacon rPi 2 do a time sync MAC --> RPI, time off by: 15.3[secs]

The drift is constant for a while, then suddenly changes, then goes away on i's own. They're both on wireless, but so are 0 and 1 and I'm not having any problems with those.

Re: rPi time drift

There is a bug in time sync. It actually does not sync.
I will post a fix in the next days.
Suggest to set the fix value high so thy you don't get the messages
