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.
Right, this isn't good.
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?
Yes. I consider allowing this invalid date a bug which will be fixed.
I was hoping is_not_a_date() would not allow 20020229.
My preference is to prevent construction of 20020229 and thus the only way to get is_not_a_date true is to construct the date explicitly not_a_date_time. Jeff
