Grrr!  Except s/you/they/; I didn't invent.

So right isn't quite, err, right.  I wonder whether the Olsen db can
be fixed to account for that?  right/UTC and posix/UTC currently are
identical for all (time_t)LONG_MIN <= time_t < 78796800.


Thanks for the reminder.  I had forgotten that entirely.  (And am 
only just vaguely remembering that I used to know that fact.  [SIGH])

Part of what makes this list's name so appropriate is just how hard
it is, all things considered.  That is also what makes it enjoyable.
