Has anyone experienced it before?
What software is producing these logs? In particular, the AT suggests
this may be using some service provided by a mobile phone.
Please confirm you have at least four, unrelated servers configured.
Please provide the result of running ntpq against your NTP client,
assuming that it is sufficiently compliant to support that.
