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!
