Abbreviation disambiguation
On Clockjumper, UTC refers to Coordinated Universal Time — the global reference from which every other zone is expressed as an offset. It never shifts for daylight saving. GMT is equivalent to UTC for everyday use, though in the UK "GMT" also names the winter time, with clocks moving to BST in summer.
