Aside from the command line, it's got a mode where tries to adjust the drift
like ntpd does. I think saves stuff on the disk so when you run it again it
can see how far the clock has drifted. I don't know how that interacts with

There are two types of outliers. One is hardware, a specific box has a weird
crystal or out of date firmware or... The other is systematic. Someplace in
the long chain of hardware, documentation, firmware, kernel, libraries, and
ntpd isn't working right. I think this one is worth understanding. If/when
we understand it, we can try to come up with a reasonable work-around.

I have it running on an OpenBSD system. It seems to wander off occasionally.
I haven't investigated.

We should probably agree to disagree.
These are my opinions. I hate spam.
