26 Mar 2007:  Richard Pellessier suggested changing YST (Yukon
Standard Time) to AKST (Alaska Standard Time);  adding a new
zone -8 for AKDT (Alaska Daylight Time);  removing CAT
(the now-obsolete Central Alaskan Time);  and adding HADT
(Hawaii-Aleutian Daylight Time;  Hawaii doesn't actually
observe DST,  but the Aleuts do.)
