Lex's idea was to have one primitive that reported both UTC and offset
as a single primitive operation. That is simple and still makes sense
to me, so if you were to implement a new primitive to replace the current
inconsistent one, this would still be my suggestion. To be honest I did
not look at the LocalePlugin implementations at all. Your question just
reminded me that the problem was "solved" long ago but never implemented.

You have to specify your local time zone in the image to select the
correct time zone table, the same as is done for an operating system.
This is not what you would want for OLPC, it's more appropriate for
e.g. a Squeak web server application.
