Here is data from a system using Google's NTP servers.
The Offset is the view from another system. The drift is from the system
Google said 13.9 uSec/sec. That matches the step in the drift.
Note the overshoot at the end of the smear. It's about 50 ms. There is a
similar blip at the start of the smear, but it's harder to see when it's
riding on top of the sloped line.
The NIST UT1 server smeared the second over a whole day. ??
Somebody asked about systems that "freeze" the clock for a second. Linux,
NetBSD, and FreeBSD all stepped the clock back. An OpenBSD system was off by
a second for about 4 hours.
These are my opinions. I hate spam.
