  Is there (E)BNF available for the date/time strings that can be shared
outside of Bull?  With that, munging the details (like easter) should
be straightforward/at least do-able.

  Also, isn't there a convert_date_to_binary_$relative_time rtn (or
something similar) which just parsed time deltas from current time?
I'm thinking of memo's "-repeat 2 weeks" argument.  Or was that just
a degenerate case of not giving a base time along with the delta in
the string?  It *has* been a while (longer than I really care to think
about)...
