Gmt Timezone
GMT is not one timezone. Live clocks: London, Lisbon, Reykjavik, Accra, Dakar. Default face: UK time (BST, UTC+0 in winter, UTC+1 in summer).
GMT is a named offset, not a town. The live clock is UK time (BST, UTC+0 in winter, UTC+1 in summer). Extra city cards appear only when those cities actually disagree.
London, Lisbon, Reykjavik, Accra, Dakar are examples of places often filed under GMT. They are not suburbs of one metro.
GMT changes on the last Sunday in March and the last Sunday in October (EU/UK dates).
When it is noon in GMT it is 7 a.m. in New York all year.
GMT sits close to the UK time meridian (0°), so clock noon and solar noon are not far apart.
Mid-January sunrise here is within a few minutes of London.

More than one timezone in GMT
London, Lisbon, Reykjavik, Accra, Dakar — those cards are different civil times. The large face is the default for GMT (UK time).
The live clock is the same TabClock face as the homepage.
