I was thinking about larger adjustments in the timezones, like 15, 30
or 60 minutes. They could be announced decades or centuries ahead, but
possibly they would be hidden in the noise of the political/religious
adjustments that are common today. Before the first correction is
needed, maybe a global fixed timezone (or UTC directly) is already
used everywhere and the position of the Sun observed at 12:00 is let
to slowly revolve around Earth.
