Map showing the member states of ASEAN.

TheASEAN Common Time (ACT) is a proposal to adopt astandard time for allAssociation of Southeast Asian Nations member states.[1][2] It was proposed in 1995 bySingapore, and in 2004 and 2015 byMalaysia to make business across countries easier.[3][4] The proposal failed because of opposition inThailand andCambodia:[3][5] Thais and Cambodians argued thatUTC+08:00 was not better thanUTC+07:00, which is the current time zone of their countries.[3]

Currently, there are four different time zones used by ASEAN countries.UTC+06:30 (Myanmar);UTC+07:00 (Cambodia,Laos,Thailand,Vietnam, andWestern Indonesia);UTC+08:00 (Brunei,Central Indonesia,Malaysia,Philippines, andSingapore); andUTC+09:00 (Eastern Indonesia andTimor-Leste).

The proposal would instituteUTC+08:00 as theASEAN Central Time, putting Myanmar atUTC+07:00, and leaving the less populous easternIndonesia atUTC+09:00.[citation needed] This would result in the vast majority of the region's people and territory lining up atUTC+08:00—in sync withChina,Hong Kong,Macau,Taiwan, andWestern Australia, while eastern islands of Indonesia would remain atUTC+09:00—in sync withJapan,South Korea,North Korea,East Timor andPalau.

Some regional businesses have already begun adopting the phrase "ASEAN Common Time", also using the abbreviation ACT, in their press releases, communications, and legal documents. The idea has since been under discussion by ASEAN, with Singapore supporting it strongly.[6][7]

Notes

[edit]
  1. ^The Philippines was one day behind neighboring countries in Asia sinceFerdinand Magellan's arrival on 16 March 1521, then later claimed part of theViceroyalty of New Spain (Virreinato de Nueva España) known as Spanish Empire on 27 April 1565 until Mexico's independence on 27 September 1821. More than two decades later, on 16 August 1844, then Governor-GeneralNarciso Claveria reformed the Philippines calendar by removing Tuesday, 31 December 1844, to align with the rest of Asia. Monday, 30 December 1844 was immediately followed by Wednesday, 1 January 1845. The change also applied toCaroline Islands,Guam,Marianas Islands,Marshall Islands andPalau for being part of theCaptaincy General of the Philippines during those times.
