Re: Date_time library question...

date bogus_date_I_hope(2002,02,29);

I was hoping the above date would not be allowed (2002 is not a leap 
year). 

However I notice that the date_time library considers this to be Mar 
01, 2002.

This is reasonable but what if I want the stricter interpretation - 
i.e, "20020229 is not a valid date".

After all the date_time library does not allow 20020232 and a not too 
unreasonable person might say "Well if 2002029 is converted to 
20020301 why isn't 20020232 converted to 20020304."

Short of creating my own logic is there a way for the date_time 
library to not accept invalid dates?

I was hoping is_not_a_date() would not allow 20020229.

If there isn't a simple way of coercing the right range for dates, is 
there some document out there that I can point to to say "Hey the 
decision to wrap a restricted range of invalid dates is quite ok - 
look at this document (from XYZ)."
