NTP client does it every 6 hours.
1 minute offset in 6 hours signifies badly damaged hardware (or that your virtualization solution does not keep time correctly)

What are your time servers? Are your domain controllers in sync?

This behaviour seems really random. Sometimes it happens 3 times a day, sometimes it does not happen in 2 weeks.

This is a physical server, and I have seen this event everywhere even on my Windows 7 machine, which syncs with Internet.

it is a normal time synching event. "Windows Time" service is responsible for it.

particular message sets time one minute ahead. That is bad. i would recommend to check (with ntpdate from meinberg NTP if no better idea) if all DCs have same time set.

This event is a sign of normal operation otherwise. If you filter then say pay attention to offset of >10min or so.

You can use Meinberg NTP to adjust timer speed in place of default NTP. It will report communication error with upstream NTP anyway.
