Yes. The kilosecond is a convenient unit of time for intra-day planning. (Metric day folks endorse the centiday, 864 s, for the same purpose.) 100 ks is a reasonable diurnal cycle. I hypothesise that a human civilisation entirely disconnected from natural diurnal cycles would use an artificial 100 ks cycle for this purpose, and a 1 Ms cycle as the analogue of our week. > How would you keep such divergent >times strait? Not sure what you mean here. Relating the SI time units to conventional time of day is messy; determining which calendar day my birthday falls on is non-trivial. In the absence of days and years, though, calculations that involve only metric units are a lot easier than what we presently put up with. >Let's meet for dinner in about 200 kiloseconds? The linear TAI time now, in my preferred notation, is 0m026. (This means 26 ks after a 10 Ms rollover. I'm dropping high- and low-order digits that don't help for the task.) Dinner will therefore be at 0m226. I'll be having some other meals before that, of course, since I don't want to starve. If we're living in an asteroid belt, the 200 ks interval is simply two sleep cycles. -zefram _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
