Author: Krzesimir Nowak <krnowak svn gnome org>
Date:   Sat Jul 18 14:35:43 2009 +0200

    Wrapped several ISO 8601 related functions.
    
    * glib/glibmm/timeval.cc:
    * glib/glibmm/timeval.h: Wrapped g_time_val_from_iso8601() and
    g_time_val_to_iso8601().
    * glib/src/date.ccg:
    * glib/src/date.hg: Wrapped g_date_get_iso8601_week_of_year().
