    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    First, convert the date to julian format (just a big number), do the date arithmetic, and convert back to a normalized date value. This algorithm from the Wikipedia works: Julian day - Wikipedia, the free encyclopedia
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
