I would not slight the efforts that have been made thus far, but to claim that the SRG has adequately made calls is hogwash. I have been trying to gather cost estimates of eliminating leap seconds, and I know that it is not easy. Much of the problem is that people do not understand how deeply their systems depend on leap seconds. It takes an enormous amount of pedagogy to motivate a response. As noted in the title of my last posting, the SRG has made too little effort in that direction. There should be detailed published explanations of systems which are known to have difficulties with leap seconds, and also of systems which are known not to have difficulties with leap seconds. The question before the SRG cannot be answered in satisfaction to everyone. Basically it amounts to asking "who do we screw, and how gently do we screw them?" So far I perceive the SRG's strategy to be inconsiderate to astronomers and posterity, among others. > William Klepczynski: In safety-critical navigation systems, leap seconds > will over time cause catastrophic system failures that will cost many > lives.

I rebut that any system whose designers cannot implement a specification as clearly spelled out as the current scheme for UTC has much worse things to worry about than leap seconds. -- Steve Allen UCO/Lick Observatory Santa Cruz, CA 95064 [EMAIL PROTECTED] Voice: +1 831 459 3046 http://www.ucolick.org/~sla PGP: 1024/E46978C5 F6 78 D1 10 62 94 8F 2E 49 89 0E FE 26 B4 14 93
