Here is data from a system using Google's NTP servers. http://users.megapathdsl.net/~hmurray/time-nuts/leap/ntp-goog-leap.png
The Offset is the view from another system. The drift is from the system itself. 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. ?? http://users.megapathdsl.net/~hmurray/time-nuts/leap/UT1-SF-leap.png 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.
