Time zones and their denomination

Every time zone has one or more denominations that are used to reference it. The most commonly used is a three-letter code, that in the case of Spain is CET (Central Europe Time). There is another less used denomination, the military, which may sound familiar due to its use in TV series and action films, according to this denomination, the Zulu hour corresponds to the time of the meridian of Greenwich. In addition to these in a third denomination, each time zone is named with the initial letter of its military name.
