A point in favor of deriving the Internet time scale directly from TAI is that it fairly effectively reduces UTC to just another time zone, one that covers the entire surface of the Earth, but a timezone nonetheless. Just like every other time zone, its future divergence from TAI is unpredictable. The principle reason is that time zones are under the control of-- and subject to change at any time by-- various sovereign and treaty bodies. TAI has a fairly stable foundation in non-relativistic physics, which experience has shown to be somewhat resistant to the power of political bodies to modify at will, so it should be good enough for most running code on the Internet. Shorter james: +1 for switching to TAI. -- james woodyatt <j...@apple.com> member of technical staff, core os networking _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
