Developers at the University of Melbourne have produced a time-sync
client called "TSCclock" which exchanges standard NTP packets with a
NTP server.  They assert that TSCclock, which runs on FreeBSD and at
least two flavors of Linux (Ubuntu and Fedora), provides substantially
better synchronization than ntpd both on a LAN and over the Internet.

The following info is some of what is available:

1. The TSCclock page at the University of Melbourne:
http://www.cubinlab.ee.unimelb.edu.au/tscclock/

2. A paper titled "Ten Microseconds Over LAN, for Free", originally
presented at the 2007 International IEEE Symposium on Precision Clock
Synchronization for Measurement, Control and Communication.  This is
available at
http://www.cubinlab.ee.unimelb.edu.au/~darryl/Publications/ISPCS07_camera.pdf
It includes a general description of their approach and results for
both ntpd and TSCclock obtained in their testbed.

3. A one-hour Google Tech Talk: http://www.youtube.com/watch?v=o3nXgeh7v_U

All of the info on TSCclock that I have run across has originated with
the group at the University of Melbourne.  Does anyone know of an
independent comparison between ntpd and TSCclock?

Thanks,
Gene
