This is the solution with least damage, letting the existing code to
set archive_time and then discard the result and overwrite with the
command line option.

I wonder if we want to use approxidate_careful() to deal with bogus
input?  The code is perfectly serviceable without it (users who feed
bogus input deserve what they get), but some folks might prefer to
be "nicer" than necessary ;-)

Other than that, looks very good.  Thanks.
