  • Time zones are geographical areas that observe the same official time
  • An offset is the difference between time in a certain time zone and Universal Coordinated Time (UTC), whose predecessor is GMT
  • GMT is itself a time zone that has 0 offset from UTC. Even after 1972, when UTC replaced GMT, the latter continued to be widely used in various fields (e.g. aviation and broadcasting)
