There is a related project http://joda-time.sourceforge.net/related.html that handles non-working days. That may be your easiest solution.
Writing a chronology is basically creating a subclass of Chronology or BaseChronology and implementing as many methods as you can/want. For example, you may only care about dates and not times. The classes in the field package provide most of the common fields that you need. The basic concept is that you are interpretting the long millisecond value to something meaningful. Its a big task though (with time zones causing even more problems).
