Looks like a good time for this question:
What are the figures of merit that we should be tracking when monitoring
the quality of servers using NTP for exchange?
I understand that these values will factor differently with different user
groups, but the characteristics we can measure should be fai

I think you have the basics: offset, dispersion, jitter, wander. Plus the

I'm sorry, but yes, you do need to do that. I'm swamped with both small
and large tasks. I have to either offload or refuse some small tasks
that others can do in order to execute tasks that presently

I noticed. The lab will be mostly 3s, which complicates the cable management
because of the switch to the side-mounted power connector.

There are also no releases on ftp://ftp.ntpsec.org/pub/releases/,
0.9.1 is the latest.

You know you can tell your Pi to use the other edge? It requires a reboot.

Folks,
I was wondering what the status was of the 0.9.3 release. I see two
checkins from Mark on the 18th which seem to indicate that development for
0.9.4 had begun, but there is not actually an 0.9.3 tag in gitlab. Was
this an oversight, or is there something being worked through?

PPS over USB will be off on average of 1/2 the polling interval. It's easy
to see if you have a decent place to stand. In some sense, it's not a big
