How do stations and networks deal with that latency between
a news anchor in the home office and a reporter in the field?
Perhaps a low-latency side channel? Eight seconds of dead
air is expensive.
I'm changing my stance on Leap Seconds: yes, it's a means of
keeping UTC synchronized with the earth's rotation. But I
see no need. Fix UTC forever at TAI - 42(?) s and make desired
adjustments in civil time. At some future date when the drift
accumulates to several minutes, change my timezone from MST7MDT
to MST7:15MDT. This can be coordinated with the Spring clock
reset: every few centuries that can be +45 minutes instead of
+60.
