If one is looking at ONLY displaying current dates, then that is not a problem, 
but why have one display process for current dates and a different one for 
historic dates? My point is that if you ask for historic dates is should be 
handled the same as a current one. Time didn't start in 1970 ... even if some 
computers still think it did.
