I don't think I like this idea anyway.  If something has units of an
hour and the user (perhaps misunderstanding the setting) sets it to one
second, then we shouldn't silently change that to one hour.

If there is a problem with rounding it to zero, then we should perhaps
raise an error.  (And stop treating zero specially.  It's a terrible idea.)
