[tz] Time zone reference inconsistencies

Jan. 6, 2015

      To whom it may be of interest:

The time zone rule files referred to following locations that are not found
in "zone1970.tab":

 America/Montreal
 America/Antigua
 America/Cayman
 Asia/Bahrain
 Asia/Kuwait
 Asia/Muscat
 Asia/Aden
 Pacific/Saipan
 Pacific/Midway

Note: some (if not all) of the above-listed locations are found in
"zone.tab", but the documentation states that "zone1970.tab" should be used
instead.

Thank you for your excellent (and much appreciated!) work. Happy new year
2015!
