計時學

• 計時學是時間科學，如時鐘（鐘錶）和計時。

• 鐘錶起源於巴比倫時代（西元前16世紀），那時候就發明了一分鐘60秒和每小時60分鐘的計時方法。

• 對於計時學感興趣的人稱為計時學家。該術語可適用於專門研究計時儀器的人們（鐘錶製造人）以及計時學愛好者和學者。

Principles of time

• In 1878, Canadian Sir Sanford Fleming proposed worldwide time zones.

– The world be divided into twenty-four time zones, spaced 15

degrees of longitude apart.

– Since the earth rotates once every 24 hours and there are 360

degrees of longitude, each hour the earth rotates one-twenty-fourth

of a circle or 15° of longitude.

– First time zone is called “UTC” (Coordinated Universal Time) at

Prime Meridian (or GMT-Greenwich Meridian Time)

時間原理

• 1878年加拿大人弗來明（Sanford Fleming）先生提出了世界時區之說。

– 全世界可分為24個時區，經度間隔為15度。

因為地球每24小時自轉一周，而緯度共分為360度，所以每小時地球將自轉1/24周或者轉過15°經度。

第一個時區叫做UTC（協調世界時）在本初子午線（即格林尼治標準時間格林尼治子午線）。

Daylight Saving Time

• Daylight Saving time (DST) or Summer Time (British) is the convention of

advancing clocks so that afternoons have more daylight and mornings have less.

• Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.

• Many countries are still using it; details vary by location and changes occasionally.

• Benefits:

– Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours

– Generally important to countries with agricultural industry

– Traffic fatalities are reduced when there is extra afternoon daylight

日光節約制

• 日光節約制（DST）或夏令時（英國）是將時鐘調快，增加下午時間減少上午時間的做法。

• 通常在春季將近開始的時候將時鐘調快一小時，秋季的時候再調回來。

• 現在有許多國家還在使用這種制度，具體情況因地點的不同也會有些許差異。

• 優點：

– 可以增加下午的時間，以便進行購物、運動和其他活動以便充分利用下班時間。

– 一般來講，對農業國家會有重要意義。

– 如果下午有更多的白日時間的話，交通就不會太擁擠。
