@ 10 - From http://www.timetemperature.com/tzus/time_zone...
The United States uses nine standard time zones. From east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
The plus on the Guam side (Chamorro) looks not to be a typo; it's borne out here: http://www.time.gov/
. On that site it also looks like we have a separate Micronesia time zone that's UTC+11. There are probably abbreviations for these less populated Pacific island time zones, but no clue as to how widespread they are.
I wouldn't write daylight saving time with a hyphen, and I'm generally pretty conservative about hyphens. I say "daylight savings time," though, with the S.
