Greenwich Mean Time (GMT) is the historic anchor of modern civil timekeeping. Established in the nineteenth century to eliminate chaotic local solar time across British railways, GMT established the 0° longitudinal meridian as the universal starting point for world time zones.
Today, GMT serves as a legal civil time zone for the UK in winter and numerous Atlantic and West African nations throughout the year. Use our live clock to verify exact GMT seconds, check business overlap, and convert times globally with complete accuracy.
