1) Get the long integer value from each of the dates (which
   represents the time in milliseconds since a fixed time, 1 Jan
   1970, I think, but it's not important).

2) Subtract the smaller from the larger number and you get the
   difference between the two dates in milliseconds.

3) Divide by 1000*60*60*24 (number of milliseconds in a day) to get
   number of days between the dates.
