Video transcript

GMT in Europe refers to Greenwich Mean Time, the time zone at the Royal Observatory in Greenwich, London. It is the same as Coordinated Universal Time (UTC+0) and serves as a reference for timekeeping worldwide. While the UK and Portugal use GMT during winter, they switch to British Summer Time (BST) and Western European Summer Time (WEST), respectively, during daylight saving time. Other European countries follow time zones like Central European Time (CET) or Eastern European Time (EET).
