RE: Date arithmetic - performance dog?

I've been curious about this as well.  I have an EDI translator program that 
does heavy date manipulation.  Granted it reads thru 3 million records on 
average, but it takes about 3-4 hours.  I know a lot has to do with how we 
prioritize our jobs around here, but since someone mentioned they thought they 
took a 40% performance hit when using date fields and date logic, I've been 
wondering.

I wanted to see if you folks have found that ADDDUR and SUBDUR (etc.), and 
MOVEing to/from date fields are REALLY poor performers - it sure seems that way 
to me.  Is there a way to make such things perform well?

TIA,
Michael
