About Central Africa Time (CAT)
Central Africa Time (CAT, IANA: Africa/Johannesburg, Africa/Harare) is the civil time for Central and Southern African countries, set at UTC+2:00 year-round (no DST). CAT serves approximately 200 million people across: Botswana, Burundi, DR Congo (eastern half), Egypt (since 2014 reverting from earlier DST trial; year-round UTC+2), eSwatini (Swaziland), Lesotho, Libya, Malawi, Mozambique, Namibia (since 2017 reverting from earlier WAT trial; year-round UTC+2), Rwanda, South Africa, Sudan (UTC+2 since 2017), Zambia, Zimbabwe. CAT shares the same UTC offset as Eastern European Time (EET) in winter, Egypt Standard Time (EET-Egypt), and Israel Standard Time (IST). Major CAT cities: Johannesburg (5.6M city, 10M metro — economic capital of Sub-Saharan Africa), Cape Town (4.7M metro), Cairo (10M city, 22M metro — the largest city in Africa and the Middle East), Khartoum (5.3M), Lusaka (2.7M), Harare (1.6M), Tripoli (1.2M), Pretoria (740K).

About Greenwich Mean Time (GMT)
Greenwich Mean Time (GMT, IANA: Europe/London) is the historic and current civil time of the United Kingdom (during winter), Ireland (during winter), Portugal mainland (during winter), Iceland (year-round), and most West African countries. GMT is set at UTC+0 — the time on the Prime Meridian (0° longitude) running through the Royal Observatory in Greenwich, southeast London. Established as the global time reference by the 1884 International Meridian Conference in Washington DC, GMT served as the world's primary civil-time reference from 1884 until 1972 when UTC (Coordinated Universal Time) was adopted as the new precision standard. The UK switches from GMT to British Summer Time (BST = UTC+1) at 01:00 GMT on the last Sunday of March and back to GMT at 02:00 BST on the last Sunday of October per EU Directive 2000/84/EC (UK retained this schedule after Brexit). GMT affects: London Stock Exchange (LSE) trading hours, BBC World Service broadcast time-stamps, all aviation NOTAMs and weather METARs which use UTC = GMT, and ICAO + IMO worldwide maritime/aviation coordination.
