However, the older version of chron DID allow creating CORRECT chron objects
with mm/dd/yyyy

[1] 10956

[1] 10957

wheras backformatting in the print method failed

[1] 12/31/99
> dates("01/01/2000", format='m/d/y')
[1] 01/01/100

thus I tend to see it as a bug, because it may break old code.

Still, I don't know whether it is approbriate to send a bug report to
r-bugs@lists.r-project.org ?
