So, again, why have we been shy of adding this to the stdlib? We did
(eventually) add the fixed offset classes. (And before you say "for the
same reason we didn't add the USTimeZone class", the reasons can't be the
same -- the latter would require maintenance whenever the US changes its
DST rules, while LocalTime is oblivious to all that.)
