Hmm, the aspect of date conversion is interesting.  In particular:

We already have bi-directional conversion between common and Epoch dates
('date +%s.%N' to convert to seconds since Epoch, and 'date -d @...' to
convert Epoch back to common).  So if we do add a conversion to Julian
date output, we should also add a -d shorthand for conversion from
Julian on input.
