This results from "script" logging backspaces into the log
file instead of deleting characters in there and my not
spotting that when cleaning up the log file. Nothing to do with
the question at hand.

Huh ? This IS different time zones from the same timestamp
within the same query, isn't it ??
The fact that different versions of PostgreSQL get it right or
wrong in a variety of ways indicates that the logic may need
to be fixed but does show that in principle it is quite
possible. If that's not what you wanted to do then I did
misunderstand your original question.
