How come you aren't screaming about the much larger local-time errors
that occur when tz updates are neglected? Those errors are thousands of
times larger! Why aren't you proposing that UNIX time_t be local time?

Eventually we'll all have the TAI-to-local-time tables automatically
updated through the network. The existing software, even without perfect
automation, already gives us accurate local-time displays---a basic test
flunked by all of your proposals whenever leap seconds occur.
