National Standard Time{{efn native lang|tw|t=國家標準時間|p=Guójiā biāozhǔn shíjiān|m=Kok-ka piau-chún sî-kan}} is the official time zone in Taiwan defined by an UTC offset of +08:00. This standard is also known as Taipei Time ({{lang|zh-Hant-tw|臺北時間}}), Taiwan Time ({{lang|zh-Hant-tw|臺灣時間}}) or Taiwan Standard Time (TST).{{cite web|script-title=zh:標準局：沒有「中原」標準時間 |url=http://home.dcilab.hinet.net/lcchen/spacenews/2005/20050111203.htm |access-date=December 12, 2016 |author=仝澤蓉 |date=2005-01-12 |language=zh |url-status=dead |archive-url=https://web.archive.org/web/20051205010456/http://home.dcilab.hinet.net/lcchen/spacenews/2005/20050111203.htm |archive-date=December 5, 2005 }}

The first time zone standard in Taiwan was enforced on 1 January 1896, the second year of Taiwan under Japanese rule. The standard was called {{nihongo|Western Standard Time|西部標準時}} with time offset of UTC+08:00, based on 120°E longitude. On 1 October 1937, the Western Standard Time zone was abolished and the {{nihongo|Central Standard Time|中央標準時}}, with time offset of UTC+09:00, was enforced in the entire country of Japan including Taiwan. This time was used until the end of the Second World War. On 21 September 1945, the Governor-General of Taiwan announced that the order issued in 1937 was revoked.:wikisource:ja:臺灣ノ標準時ニ關スル件 (昭和二十年台湾総督府告示第三百八十六号) Time Memorial Day was observed every 10 June from 1921 to 1941, which led to an increase in the observance of an official time.{{cite news |author1=Han Cheung |title=Taiwan in Time: Colonial masters of time |url=https://www.taipeitimes.com/News/feat/archives/2020/06/07/2003737772 |access-date=7 June 2020 |work=Taipei Times |date=7 June 2020}}

After the war's end, Taiwan was annexed to the five time zones system of the Republic of China. It was classified in the "Chungyuan Standard Time" with a time offset of UTC+08:00. After the Chinese Civil War in 1949, the Government of the Republic of China retreated to Taiwan and lost nearly all the territory in mainland China. Since then, the five time zones system was no longer implemented except for the Chungyuan Standard Time in Taiwan. Because the term "Chungyuan" (Zhongyuan) refers to the Central Plain of China, the government gradually phased out the name in favor of "National Standard Time". However, some radio channels continued using "Chungyuan", most notably the Broadcasting Corporation of China until 2007.{{Cite web|url=https://news.ltn.com.tw/news/life/paper/22980|title=中原標準時間 早已不適用 - 生活 - 自由時報電子報|date=2005-06-25|website=自由電子報|language=zh-Hant-TW|access-date=2020-04-01}}{{Cite web|url=https://news.tvbs.com.tw/politics/338067|title=「中原標準時間」 中廣報時不復見|website=TVBS|language=zh-tw|access-date=2020-04-01}} Other alternatives include "Taiwan Standard Time" ({{lang|zh-tw|臺灣標準時間}}) and "Taipei Time" ({{lang|zh-tw|臺北時間}}).

Daylight saving time was implemented in Taiwan after the Second World War on the summer of 1946–1961, 1974, 1975, 1979.Yu-Cheng Chuang (Jul 11, 2014) [台灣日光節約時間之考據 https://blog.yorkxin.org/posts/2014/07/11/dst-in-taiwan-study/]

In October 2017, a petition took place to change the offset to UTC+09:00, which was responded by an assessment of potential impact by the government.{{cite web|title=我國應調整時區至GMT +9|url=https://join.gov.tw/idea/detail/90028e3c-f785-438a-836b-25b0b8fb8e1b|website=join.gov.tw|access-date=1 January 2018|language=zh-Hant}}
