[commit: old-time] master: Make %j return values in the right range; fixes #5430 (3669ee6)

Repository : ssh://darcs.haskell.org//srv/darcs/packages/old-time

On branch  : master

http://hackage.haskell.org/trac/ghc/changeset/3669ee6fd9cfbec4d8f3b5e5f8862b864f427b7f

>---------------------------------------------------------------

commit 3669ee6fd9cfbec4d8f3b5e5f8862b864f427b7f
Author: Ian Lynagh <igloo <at> earth.li>
Date:   Fri Sep 30 12:27:06 2011 +0100

    Make %j return values in the right range; fixes #5430

    Both "struct tm" and the CalendarTime type use 000-365, but %j
    uses 001-366.
