My point was that I believe the current list of offered solutions are not wild enough. If the SRG had clout I would expect to see it persuading the Galileo system to adopt TI = UTC at the time of launch, and then I would expect to see them persuading the GPS maintainers to switch GPS time to match that Galileo TI as a part of the next GPS W1K rollover. Or I would expect to see them convincing Galileo to adopt GPS time. Otherwise I would like them to be explaining why these are not feasible. Something that does seem obvious from the colloquium is that TAI is absolutely, definitely doomed except as a historical footnote. Only the Galileo system design argues for its continued notice by anyone. That is not the result that I would have expected. > If memory serves me right, this came out of William Klepczynski's talk, > but I don't recall specific examples being given there.

If only PowerPoint presentations are posted in the absence of detailed written arguments and references to published discussions then the colloquium is pedagogically and archivally barren.

At their day jobs most of the SRG seem more deeply involved with technology than with pedagogy and dialectics. This is certainly a noble (and possibly even a Nobel) cause, but as they say here in Santa Cruz, legislators and their constituencies will want to "Question Authority". This is especially so if it means their garden sundials will diverge and their descendants will be handed a problem to solve. > Just look at the sorry state of the use of SI > units in United States legislation to get the idea. We do use SI units. 1 (international) inch is defined to be 0.0254 m. This is accomplished permanently without causing grief or needing anyone ever to notice. Inexorably changing the time of noon is not the same. That will require significantly more legislative attention, persuasive justification, and refutation of rebuttals. Nothing of this sort has not been forthcoming so far. -- 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
