It isn't quite that easy as the date field is a bitpacked struct
holding the year, month and day.  So you have to account for month and
year boundaries.  In the absence of any other ideas or tips to where I
can find a function to do this for me, I implement the calendaring
increments and send a patch which follows the above idea.
