About Indochina Time (ICT)

Indochina Time (ICT, IANA: Asia/Bangkok, Asia/Ho_Chi_Minh) is the civil time of mainland Southeast Asia (excluding Myanmar + Indonesia), set at UTC+7:00 year-round (no DST). ICT serves approximately 250 million people across: Thailand, Vietnam, Cambodia, Laos, Christmas Island (Australian territory in Indian Ocean), Java + Sumatra + western Indonesia (which uses Western Indonesian Time WIB = identical UTC+7 offset). ICT shares its offset with Krasnoyarsk Time (Russia, UTC+7) and Davis Antarctica research station. Major ICT cities: Bangkok Thailand (10.7M metro — Southeast Asia's largest tourist destination + ASEAN economic hub), Ho Chi Minh City Vietnam (10M city, 14M metro — formerly Saigon, Vietnam's largest city), Hanoi Vietnam (8M metro — capital), Jakarta Indonesia (10.5M city, 35M metro — uses WIB which is identical to ICT but a different zone-name), Phnom Penh Cambodia (2M), Vientiane Laos (820K). Affects: SET (Stock Exchange of Thailand) trading hours, HOSE + HNX (Vietnam stock exchanges) trading, Phnom Penh Securities Exchange (CSX) hours, Bangkok BTS Skytrain + MRT subway operating hours, and ASEAN diplomatic-meeting schedules.

About Brasília Time (BRT)

Brasília Time (BRT, IANA: America/Sao_Paulo) is the official civil time of Brazil's most populous regions, set at UTC-3:00 — named after the federal capital city of Brasília. BRT serves approximately 175 million people across 23 of Brazil's 26 states + Federal District including the megacities São Paulo (12M), Rio de Janeiro (6.7M), Salvador (2.9M), Fortaleza (2.7M), Belo Horizonte (2.5M), Brasília (3.1M), Curitiba (1.9M). Brazil abolished Daylight Saving Time in 2019 by Presidential Decree 9772/2019 (citing minimal energy savings and disruption costs), so BRT is observed year-round without seasonal change since then. Acre State and a small portion of Amazonas use Acre Time (ACT = UTC-5:00); the remainder of Amazonas plus Mato Grosso/Mato Grosso do Sul/Rondônia use Amazon Time (AMT = UTC-4:00); the Fernando de Noronha archipelago uses UTC-2:00. BRT affects: B3 (São Paulo Stock Exchange) trading hours, Brazilian football Série A match scheduling, and Petrobras / Vale international corporate-call timing.
