You should consult this thread. It has a whole bunch of questions about date.

// Date d;
// const int SECS_PER_MIN = 60;
// const int MIN_PER_HR = 60;
long hours = (d.getTime() / (SECS_PER_MIN * MIN_PER_HR))

Date.getTime() returns how many seconds have passed since 1/1/1979. So that equation just converts it to hours. You never specify a reference point, you may need to add or subtract a fixed amount of hours.
