It's not about understanding the difference between earth rotation
and time. It's whether civil time shall be tied to one or the other or
to a compromise between them.

My view, of course, is that civil time should be made up of days each of
which is exactly 86400 SI seconds long. When it becomes inconvenient in
a given locality, say New York City, to say that LCT is 5 hours behind
universal time, then let the number of hours in the offset be changed.
Since the offset is already being changed twice a year, a rare secular
change should not be difficult.
