Is GMT the same as UTC?

GMT and UTC share exactly the same numerical offset — both represent UTC+00:00 — but they are fundamentally different in nature. UTC is an atomic-clock-based international time standard used as the global reference, while GMT is a geographic time zone legally observed by specific countries including the United Kingdom and Ireland during winter months.
