Currently, there are four different time zones used by ASEAN countries, such as UTC+06:30 (Myanmar); UTC+07:00 (Cambodia, Laos, Thailand, Vietnam, and western Indonesia); UTC+08:00 (Singapore, Malaysia, Brunei, Philippines, and central Indonesia); and UTC+09:00 (eastern Indonesia). The proposal would institute UTC+08:00 as the ASEAN Central Time, putting Myanmar at UTC+07:00, and leaving less populous eastern Indonesia at UTC+09:00. This would result in the vast majority of the region's people and territory lining up at UTC+08:00—in sync with China, Hong Kong, Macau, Taiwan, and Western Australia, while eastern islands of Indonesia would remain at UTC+09:00—in sync with Japan, South Korea, North Korea, East Timor and Palau.
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.
