Change ordering of HAVE_TM_ZONE and HAVE_INT_TIMEZONE code blocks
to give HAVE_TM_ZONE priority. This fixes glibc2 machines and any other machine which passes both tests in configure. Repair HAVE_TM_ZONE code which stuffs tm structure with date type values. Same problems as were originally there before v6.1, but never noticed. Thanks to Oleg for nagging :)
