Thank you for taking the time to submit a report.  However I think you
are confused by the documentation.  :-)

Here is what the standards documents say about it.

  http://www.unix-systems.org/single_unix_specification_v2/xcu/date.html

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

The algorithm is explicit that %C is the two digit century part of the
current year.  This is not the same as the 20th or 21st century
definition.  It is instead used to slice up the date into component
parts.

For example, this should return the current year.

  date +%C%y
  2004
