Overview & Capabilities

London is the historical home of the Prime Meridian at Greenwich Observatory, serving as the benchmark for Greenwich Mean Time (GMT, UTC+0). During the summer, London advances one hour to British Summer Time (BST, UTC+1). As a transatlantic financial bridge connecting Asian morning markets with Wall Street afternoon trading, London standard time represents one of the most critical coordinates in international business.
