Thanks for the report.  However, this is not a bug.

%C does not mean the century in common parlance, rather, according to
POSIX, it means:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/date.html

> 
> %C
>     Century (a year divided by 100 and truncated to an integer) as a decimal number [00,99].

Yes, the mnemonic is using century for lack of a better term, but it is
correctly printing all but the last two digits of the year.
