We simply decided which timezones we wanted to refer to by "name". Offsets (civilian or military) would be used for the rest. So we decided on all North American timezones for names, along with Greewhich Mean Time. (I'd guess that GDT means Greenwhich Daylight Time, but suspect there really is no such thing.) >"North America" included the far east of Canada as well as Alaska and Hawaii. Alaska swings *very* far west. None of us knew the names of their zones. It turns out the next zone east of EST is Atlantic Standard Time. I think I found that in a dictionary, and maybe also the Newfoundland zone. >The western extremes were more challenging. I could not find any reference to their names. I was working at The Rand Corporation at the time. It was famous for "inventing" the technical research library and it had a reference librarian who was legendary for finding difficult answers. >So I gave her a call and asked for her help. She called back in 10 minutes with the answer. I could not believe how quickly she solved this, so I asked how she came up with the answers. >She said she called the telephone information operators in the relevant areas and asked them what they called their timezones... - [8] ''日付/時間のサポート'' - [9] 上表には米軍規格のラテン文字1文字で表す方法は、 [CODE[Z]] を除いて載せていない。 [[RFC822の日付形式]]を参照。 - [10] 上表では[[電子メイル]]関連の [[RFC]] などに載っていればその番号を参考として加えた。番号がないものは、 RFC には無いものの実際には使われていたもの ([CODE[JST]] など。) と、 [[C]] のような電子メイル以外の形式, その他日付系の応用で使われていたものを含む。
