  New Revision: 18739

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=18739

  Log:
    * configure.in: always check timezone().
    * strftime.c (rb_strftime): prefer timezone/altzone rather than
      gettimeofday().  The second argument to gettimeofday() is ignored
      on Solaris.
