John is evidently quite right about the ICAS' proposal being one that would 'destroy' key characteristics of the SI system, such as coherence and consistency.
However, if one approaches this as a proposal that would *change* the SI system in this regard, then it would be worthy of consideration (this is evidently wishful thinking...). So, instead of considering the 'chron' as an "addendum" unit to the SI, I'd propose that it be considered as a *replacement* for the second itself! But I do have serious reservations about this proposal as it unfortunately does not follow the basic fundamental KISS principle. It's indeed far too complicated for the Joe Six pack on the street to follow or relate to. Therefore, Mr. Stone, please take my comments as constructive criticism. I'd simply forget about this business of t, tt, t before, t after, etc. I'd just stick with defining the chron as 0.864 of a second and define time as having 100 000 chrons in a day, write a clock like HH:CCC and get it over with! Simple, direct to the point. The trick though starts with changes to the calendar. I'd vehemently condemn ANY attempt to change the 7-day weekly cycle as it was proven disastrous in the 18th century, and we should NOT make that same mistake again. Since we're at it, let me propose that you consider a change to the calendar system that would finally address the difficulty in stating time overall as we normally do with any other measurement. Since we're... "dreaming" here, why not make a proposal that would allow us to finally write time thusly: YYYY:M:DD:HH:CCC? In the above-proposed framework we would have 10 months of 36-37 days (odd months would have odd days, even months would have even days) with corrections made as we do nowadays when it comes to adding leap days. I'm honestly not sure if we could do better than that... :-S Sincerely, Marcus On Tue, 9 Jul 2002 18:11:44 kilopascal wrote: >2002-07-09 > >Ron, > >Many have come along with ideas on reforming out present system of measuring >time.
