I would accept a patch with tests to LocalDate for conversion to/from
ModifiedJulianDays, but not Julian (as Julian days start at 12:00,
which isn't very helpful).
To patch, download the source code from svn, edit it, and then use
"create patch" in svn/Eclipse to create the patch. tests are needed
too!
