What is the easiest way to calculate the difference, in hours, between two Dates?
eg : 12 December 2004 - 15:42 pm and 18 December 2004 - 11:36 am

Date has a .getTime() method, which returns the milliseconds representation of the time. calculate the millisecond difference, then divide by 3600000 to get difference in hours.
