The kernel clock counts ticks. The ticks are relative to Epoch, which
is UTC. Ticks are what you see in the output of dmesg. So maybe call
it UTC, GMT or Zulu?

The NTP folks call them timekeepers when they are correct, and
falsetickers when they are incorrect. But "them" are timeservers
participating in the NTP protocol. See
<https://www.ntp.org/reflib/papers/ptti.pdf> and RFC 5905,
<https://datatracker.ietf.org/doc/html/rfc5905>.

If the OS is not keeping accurate time, then I would call it a falseticker.

If you only boot two computers, then you cannot be sure which computer
is the falseticker. You need three or more time sources to determine
which is the falseticker. As the saying goes, a person with a watch
knows what time it is. A person with two watches is never sure.
