GregorianCalendar fixes

[Dalibor Topic]

after the discussion on the Classpath mailing list, I'd say it looks good ;)

Mark, can I check it into Classpath's CVS with an updated ChangeLog entry?

2003-11-29  Guilhem Lavaux <guilhem@kaffe.org>

  	* java/util/GregorianCalendar.java (computeTime):
  	12:00 midnight is AM and 12:00 noon is PM.

cheers,
