Ada Calendar oddity <was Re: C date package>

[randhol+nospam@pvv.org (Preben Randhol)]

I was looking yesterday in the RM and found that Year in the
Ada.Calendar was defined until 2099 only. I have search on deja, but I
cannot find any reason for it to be defined only to 2099.

Some would claim that 2099 is a long way in the future, but I think it
isn't in all respects.

An example: If I were to make a program for issuing drivers licenses
here in Norway there would be a problem. Well not immediately but in
only 18 years.

The reason is that driver's licenses expires as you get 100 years old. So
mine expires in 2073.

If one wanted to use the Year type in Ada.Calendar for birthday and
expiration date, one would get an constraint error when one issued
drivers licences for these born this year. Wouldn't one?

I may have missed some thing important when I speedily "read" the
Ada.Calendar, but this seems a bit odd to me (the upper limit that is).
