Task: Question Answering
Input (English): passage: The IANA time zone database contains one zone for the United Kingdom in the file zone.tab, named Europe/London. This refers to the area having the ISO 3166-1 alpha-2 country code ``GB''. The zone names Europe/Guernsey, Europe/Isle_of_Man and Europe/Jersey exist because they have their own ISO 3166-1 alpha-2 but the zone.tab entries are links to Europe/London. There are several entries for UK possessions around the world.
 question: is all of the uk in the same time zone?
Output (English): Yes
