Used in: Cuba.
Cuba and the U.S. Eastern Time zone usually show the same clock time. Cuba sets its own daylight-saving rules, so the schedules could diverge, and historically they sometimes have. In recent years, however, Cuba's DST transition dates have largely matched those used in the United States, so Havana and Miami have generally remained on the same time year-round.
