Pardon me, but I'm missing something in this about the annoyance
of leap seconds. I thought the trouble was that they interrupt the
broadcast time scale (which I distinguish from UTC).
If the ITU-R decides to bless a new time scale like TI, then POSIX
can take note and say as of then time_t is to be interpreted as the
internationally-blessed broadcast time scale named TI. Bureacracy
that happens to have specified UTC can be reinterpreted on a case
by case basis to decide whether it wants TI or UTC, but in the
interim all the operational systems keep on working.
If leap seconds go into zoneinfo, then they are only as much nuisance
as when the political princes of the world decree a change in the
rules for time zones, and not even total unanimity within the ITU can
I agree that the current system is dysfunctional.
I typically carry around 100 GB of storage, a GHz of processing
capability, and devices that can communicate with 4 different
wireless protocols. That is how the world has changed since 1970
when everything was pencil, paper, and slide rule. My devices can
receive something like TI, use it internally, and report to me something
with added timezone offsets.
But of those wireless protocols, one of them was entirely shut down
by the FCC before I had owned the device 5 years, so that one is defunct
and the hardware deserves replacement.
I don't want to see mean solar time abandoned because of the
of systems with that sort of lifetime.
