History

Taiwan used Western Standard Time (西部標準時 Seibu Hyōjunji) of UTC+08:00, based on 120° longitude, from January 1896 to September 1937 under Japanese rule. It was the same UTC+8 as Taiwan uses today. However Taiwan switched to Central Standard Time (中央標準時 Chūō Hyōjunji), the UTC+9 time used by Japan, from October 1937 until 1945 until Japan lost Taiwan after World War II.

After the Republic of China (ROC) migration in 1945, Taiwan went back to Chungyuan Standard Time (中原標準時間) (UTC+8). Although the ROC government was defeated in the Chinese Civil War a few years later, and retained its authority on Taiwan only, it still uses the name "Chungyuan", as people called it before the war. As there are highly political implications, implying the five different time zones when the ROC was still ruling China, the term "Chungyuan" has become less and less popular in Taiwan. Recently, both government and citizens abandoned the use of the name "Chungyuan", and various alternatives including Taiwan Standard Time, Taipei Time, and even Formosan Time (寶島時間) occur. Though never officially announced, National Standard Time is believed to be the current official name of the time zone in Taiwan.

Present development

National Standard Time is now managed by the Bureau of Standards, Metrology and Inspection (BSMI) under the Ministry of Economic Affairs.[2] The time is released according to the caesium atomic clocks aggregated by National Standard Time and Frequency Laboratory under Chunghwa Telecom after consulting the data provided by Bureau International des Poids et Measures.[3][4]

National Standard Time used in Taiwan is also the same as that used in the PRC, including its two territories of Hong Kong and Macau. All four places, however, have their own authorities managing the time.

IANA time zone database

The IANA time zone database contains one zone for Taiwan, named Asia/Taipei.
