Greetings! I hope this question has not been posted yet. If so, I missed it even though I looked in Deja News. What is the effect of the Y2K problem on date calculations in Ada (both 83 and 95). If this is a compiler vendor issue, what compilers have "certified" their date calculations Y2K correct? I also note that the Ada 95 LRM (RM96;6.0) Ada.Calendar package defines the Year_Number as range 1901..2099. What happens in 2099? The world ends? Thanks, John Cupak Raytheon
