List of GMT offset time zones

This list contains 38 GMT offsets. Don't forget, this list is not constant (depend on, is daylight saving time applied or not).
But what is GMT? It is abbreviation for Greenwich Mean Time. GMT is the mean solar time at the Royal Observatory in Greenwich (London, UK). It was formerly used as the international civil time standard. Time zones on east from Greenwich have positive offset and on west: negative.
