Users of the metre don't rely on the form in which its definition is expressed. They rely on its length being consistent. The various redefinitions of the metre have all preserved its length, to the precision measurable at the time. The fact that UTC is a close approximation to UT is a visible feature on which users can rely. We might be able to loosen the target bound on DUT1 a bit (though that's a tricky business), but making it completely unbounded would be a gross violation of the concept and visible behaviour. The kind of places you're talking about that refer to "UTC" by name, the ones that don't really need UTC, are the same kind of places that refer to "GMT" by name and then actually use UTC. We've talked about this kind of confusion quite a bit. In non-technical discourse, "UTC", "GMT", and "UT" are effectively synonymous and all vague. So if TI is defined by that name, we can expect that this pattern will continue: "UTC", "GMT", "UT", and "TI" will (in those contexts) be effectively synonymous, and even vaguer, covering all flavours of UT and also TI. If, as you suggest, TI is defined but takes over the name "UTC", the terms (in non-technical contexts) will still widen thus in meaning, there'll just be one fewer term being used vaguely. You can't fix this problem of incorrect nomenclature usage by changing the meaning of one of the names. Please don't damage the nomenclature for those who use it successfully. -zefram _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
