[36] [[世界各国]]では、それぞれの色々な[[時刻]] ([[標準時]]) が使われています。
[[時刻]]を相互に変換したり、他の地域の現時刻を調べたりするために、
[[時差]]を示して[[標準時]]を換算するための[[表]]や、
同じ[[標準時]]の地域 ([[時間帯]]) を示した[[地図]]が作られてきました。

[229] 
各国の[[政府機関]]の[[地図]]・[[海図]]部門や軍事部門などは、世界各国の[[標準時]]情報を収集し公開している場合があります。
特に [[CIA]] の [CITE@en[World Factbook]] に収録されているものが有名です。

[230] [[ITU]] は加盟各国の最新の[[標準時]]・[[夏時刻]]の情報をまとめて公開しています。
しかし国際通信のために用いるべき時刻を示しているだけで、各国の[[法令上の時刻]]の完全な一覧表では無いようです。

[231] 
その他にも民間で色々な表や地図が作成されています。

-*-*-

[232] 
歴史的変遷は、いくつかの[[書籍]]や[[データベース]]が収集を試みているようですが、
不完全な部分も多いようです。
情報の正確性・完全性、[[媒体]]・表現形式、歴史的変遷の有無は様々ですが、
次のような[[データベース]]が存在します。

[FIG(short list)[
- [[Time Changes]] シリーズ
- [[Shanks & Pottenger]]
- [[tzdata]]
- [[timeanddate.com]]
- [CITE[Wikipedia]]
- [[Windows時間帯]]
]FIG]

[251] 最新の[[時差]]情報は色々な分野で必要とされまとめられてきましたが、
変遷情報はあまり関心を持たれてこなかったようです。

唯一必要としてきたのが[[占星学]]の一部で、
[[誕生]]の[[時刻]]を正確に把握するために当時の[[時差]]の情報が必要とされました。
[[Time Changes]] シリーズも [[Shanks]] も、[[占星術]]分野で情報が収集され、出版に至っています。

近年新たにこの分野に進出したのが[[計算機科学]]者であり、
[[計算機]]上で過去から将来にわたって[[時差]]を適切に取り扱うため、
[[tzdata]] などの[[時差]]変遷データベースが[[機械可読]]な形で編纂されています。

-*-*-

[233] [[Web]] を検索するといくつか[[時差]]や[[標準時]]の情報を提供する
[[Webサイト]]が出てきますが、多くは [[tzdata]] その他の情報を機械的に表示しているだけで、
独自の情報源を持っていないようです。

[252] [[Wikipedia]] は各言語版に世界各地の[[標準時]]やその変遷の記事がありますが、
不完全で内容の充実度も項目ごとにばらばらです。 [[tzdata]] の内容のコピーもあれば、
独自の情報を示しているものもあります。

[167] [[標準時]]と[[時差]]については、次の各項を参照:
[FIG(short list)[
- [[標準時]]
- [[時差]]
- [[時間帯の接続]]
]FIG]

-*-*-

[186] こうした[DFN[時差の表]]や[DFN[時間帯図]]は、
その時代の人々がどのような[[時刻]]を使っていたのか、
あるいは各地の[[標準時]]の[[時差]]をどのように認識していたかを伝える貴重な史料です。

[272] 各図表には、製作者の[[政治的]]立場が反映されている可能性があることには注意が必要です。
例えば [[CIA]] の[[時間帯図]]では、
[[クリミア]]は[[ウクライナ]]と同じ色で塗られています。
しかし[[クリミア]]には[[ロシア連邦]]が進攻し、併合した後[[ロシアの標準時]]が実施されています。
[[CIA]] がその事実を把握していないとは考えづらく、
併合の承認と取られかねない変更を加えられなかったのでしょう。

[273] 
そうでなくても、[[冷戦]]期の[[西側]]の[[地図]]には、
[[東側]]の最新の情報が入ってきておらず古いままとなっているケースがみられます。

[FIG(list)[
- Formosa / [TZ[+09:00:00]] / I.T.B.
- Japan / [TZ[+09:00:00]] / Since January, 1888, this time has been used
for all purposes.  It is regulated daily by a 
time signal sent to all telegraph stations.
- Korea / [TZ[+09:00:00]] / I.T.B.  O.D.
]FIG]

[FIG(list)[
- India / In towns and villages in many parts of India, local and
other time is announced by clocks striking, gongs, bells,
guns―these signals being given from churches, treasury
buildings, forts, telegraph offices, etc.  Local time is
determined for each place, where there is a Government
telegraph office, with reference to its meridian, as so many
minutes (the nearest minute to the exact time being
taken) in advance of or behind the mean time of the
Madras Observatory, which has been adopted as the
standard time for the whole of India.  This time is telegraphed
daily from Madras to every telegraph office.
Section XII. of the ‘Indian Telegraph Guide,' published
in Calcutta, consists of a closely printed table extending
over forty-nine pages, showing the difference between
Madras time and local mean time for all Government
telegraph offices in India.
- / Madras time is used on through lines of railway, and in
recording the time of despatch of foreign telegraphic
messages.  For all other ordinary public and official
transactions, as well as private business, local time is
employed.  To this, however, there appear to be exceptions,
as in Rajputana, Delhi, Umballa, Simla, etc., where
Madras time is employed for all purposes.  O.D.
- / The determinations of the difference between Madras time
and Greenwich mean time are as follows:―
-- Series A. [TZ[+05:20:59.750]] ±0.155
-- Series B. [TZ[+05:20:59.010]] ±0.163
-- Series C. [TZ[+05:20:59.115]] ±0.0227
-- Series D. [TZ[+05:20:59.233]] ±0.127
-- Series E. [TZ[+05:20:59.421]] ±0.125
- / Series C. is the most recently determined, and probably the
most accurate.  (Meteorological reporter to the Government
North-West Provinces and Oudh.)
- / The Director of the Madras Observatory gives [TZ[+05:20:59.4]],
as the most correct.
- / Ajmere / Merwara / Madras time is used, but at the Ajmere Observatory the time
used is 22m. later than this.  O.D.
- / Baluchistan / Quetta / [TZ[+05:20:59.4]] / Madras or railway time.  O.D.
- / Bengal / Calcutta / [TZ[+05:53:20.77]] / This time is in ordinary use at Bankura,
Bhagalpur, Burdwan, Darjiling, Dinajpur, Hooghly, Howrah, Jalpaiguri,
Jessore, Khulna, Malda, Midnapore, Murshidabad, Nadiya, Rajshahi, the
Twenty-four Parganas.
Madras time is used for railways and telegraphs.
It is also used by the public at 
Champaran, Darbhanga, and possibly
other places.
A local mean time is also in use.  O.D.
- / Bombay, Colaba Observatory / [TZ[+04:51:15.7]] / L.T.S. This is local mean time used at the

(時期による違いなのかどうかは不明。)

[105] 昭和12年となっていますが、図左下の小改正欄に16年とあり、実際には1941年時点のものと思われます。
(昭和12年から16年の間に起こった[[西部標準時]]や[[南洋群島東部標準時]]の廃止が反映されています。)

[191] 販売者の説明文に[TIME[1893年][year:1893]]と書かれていますが、
世界各国の[[標準時]]制定時期を考えると、明らかに誤りです。

[FIG(list)[
- [[樺太]]全島と[[北方四島]]を含む[[千島列島]]が[[ソ連]]領で [TZ[+11:00]] に塗られているようです。
- [[日本]]の本土、[[南西諸島]] ([[先島諸島]]以外)、[[伊豆諸島]]南部らしきエリア、
[[朝鮮]]は、 [TZ[+09:00]] で塗られています。
- [[カロリン諸島]]の西部が [TZ[+09:00]]、[[小笠原群島]]・[[火山列島]]、[[南鳥島]]、
[[マリアナ諸島]]・[[グアム島]]が [TZ[+10:00]]、[[カロリン諸島]]東部が [TZ[+11:00]]、
[[マーシャル諸島]]が [TZ[+12:00]] で塗られているように見えます。
[[ウェーク島]]は (画像では潰れて判読し難いですが) [TZ[+12:30]] のように見えます。
- [[支那]]の大部分、[[台湾]]、[[先島諸島]]、[[フィリピン]]、[[越南]]は [TZ[+08:00]]
で塗られています。
- [[タイ]]、[[カンボジア]]、[[ラオス]]は [TZ[+07:00]] で塗られています。
- [[西マレーシア]]・[[シンガポール]]は (画像では潰れて判読し難いですが)
[TZ[+07:30]] とされているようです。
- [[ボルネオ島]]は[[東マレーシア]]と[[インドネシア]]で[[時間帯]]の境界線が引かれていますが、
[[東マレーシア]]側の[[時間帯]]はよくわかりません。元々判別しにくい色ですが、
[[英領北ボルネオ]]が [TZ[+08:00]]、それ以外が [TZ[+07:00]] となっているようにも見えます。
(しかしその境界線は引かれていません。[[インドネシア]]との国境が海岸に近いのでよくわかりません。)
- [[インドネシア]]は6区に分かれています。[[東ティモール]]国境は描かれておらず、
[TZ[+08:00]] に属しているように見えます。
- [[ビルマ]]は [TZ[+06:30]] で塗られています。
- [[インド]]、[[ネパール]]、[[シッキム]]、[[ブルネイ]]、[[セイロン]]、
は [TZ[+05:30]] に属しています。 (やはり不鮮明ですが) [[アンダマン諸島]]、[[ニコバル諸島]]も
[TZ[+05:30]] に見えます。
- [[東パキスタン]]は [TZ[+06:00]]、[[西パキスタン]]は [TZ[+05:00]] で塗られています。
- [[チベット]]西部と[[ウイグル]]は、 [TZ[+06:00]] で塗られています。
[TZ[+08:00]] との境界は[[経度]]的な境界よりかなり[[チベット]]側に寄っています。
- [[外蒙古]]は3区に分かれています。境界線は[[経度]]ベースですが、直線ではありません。
]FIG]

[192] さて、他資料より、
[FIG(list)[
- [[マレーシア]]と[[シンガポール]]は1982年に [TZ[+08:00]] に統一されました。
[TZ[+07:30]] となっているということは、それ以前の情報に基いています。
- [[インドネシア]]は1964年から3区になっています。6区で描かれているということは、
それ以前の情報に基づいています。
- [[仏印]]は[[インドシナ戦争]]で混乱していました。
[[南ベトナム]]は1955年から1960年に [TZ[+07:00]] を使っていましたが、
その前後の時期は [TZ[+08:00]] を使っていました。
[[北ベトナム]]は [TZ[+07:00]] を使っていました。
[[南ベトナム]]を支持していた[[西側]]で作られた地図なら、[[越南]]全域を [TZ[+08:00]]
で塗っていた可能性があります。
一方、[[カンボジア]]や[[ラオス]]は [TZ[+08:00]] から [TZ[+07:00]]
に1955年前後に移行したとされています。
- [[ウイグル]]と[[チベット]]が [TZ[+08:00]] に移行した時期は完全には明かされていませんが、
1960年頃と推測されています。
- [[パキスタン]]は1951年に [TZ[+05:30]] から新[[標準時]]に移行しました。
それ以後の情報に基いています。
]FIG]
... ということから、およそ1950年代に作成されたのではないかと思われます。

> 標準時
> +はグリニジ時よりも遅れ, -は進んでいることを示す。
標準時は, その国の特殊事情や地方境界などによって,
必ずしも経度線に平行な区分に従ってはいない。
とくにソヴェト連邦では一年中夏時間を採用しているため,
全部1時間のずれがある。
すなわち, モスクワ付近は東経30°でグリニジ時より2時間進んでいる区域にあたるが,
実際は3時間進んだ区域となっている。

Chennai.  This was 5h.20m. 50 ahead of GMT.  On 1 January
1906, half an hour time zone was introduced and Indian
Standard Time was related to 82°:30' East longitude.  Therefore,
