History
How Guinea-Bissau keeps time.
When Guinea-Bissau gained independence from Portugal in 1974, it inherited the GMT (UTC+0) timezone used by its colonial administration — a legacy of Portugal's connection to the WET (Western European Time) zone, applied practically to its West African territories.
Unlike many African nations that have shifted zones to align with neighbors or political allies, Guinea-Bissau has kept its clocks unchanged through any recent history; no major re-alignment or DST introduction to report.
