That might work for intervals, but not dates or times.

'double' is just fine for intervals.  'long' is not at all fine for dates or 
times.  I outlined the reasons upthread, which apparently you ignored, but the 
bottom line is that you have to reinvent 'java.util.Calendar' if you use 
'long' to represent date/time types, and it's not typesafe.  Really bad idea.
