They may suck for being a Stratum-1/2 server, but even the most jittery Cisco is still far and away good enough to serve up a ntpdate so that an end-user PC-class machine is in the right minute.
As long as the end-user is made aware that the accuracy of said NTP clock is +/- 30.000 seconds (or whatever jitter might exist). Seems kind of ridiculous to use an NTP source that is, for many purposes, wildly inaccurate. For my purposes, wildly is more than +/- 0.1 seconds. Trying to troubleshoot a problem, network or server, where the timestamps on each server/router/device vary inconsistently, is like walking on broken fluorescent bulbs -- painful and dangerous to one's health. --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman () angryox com http://www.angryox.com/ ---------------------------------------------------------------------------
