There is an interesting thread at http://groups.google.com/group/comp.protocols.time.ntp/browse_thread/thread/30a0f68a30f83f1e/
in which Bruce Penrod notes that some of their customers didn't configuree their CDMA cell phone basestations right: We are pleased to announce that our GPS NTP servers and our CDMA NTP servers configured in user leap mode performed the leap properly this afternoon. We are aware that some of the cellular basestations set the leap second a day early, and some PCS basestations have still not set it. We regret that some customers apparently had not configured their NTP servers to operate in user leap second mode, and apologize for any problems this might have caused. David L.

I also note this at http://www.eecis.udel.edu/~mills/ntp.html: Recently, the precision time kernel support now incorporated in the kernels for Tru64, Solaris, Linux and FreeBSD has been updated to improve accuracy and resolution to the nanosecond. In addition, a plan has been worked out with NIST for the distribution of International Atomic Time (TAI) via NTP using the Autokey protocol. I'd love to see TAI over NTP, and am glad to see some motion in that direction. Anyone know more? Cheers, Neal McBurnett http://bcn.boulder.co.us/~neal/
