UTC±00:00 is the following time:

• Coordinated Universal Time, the basis for the world's civil time, occasionally referred to by the name of its predecessor, Greenwich Mean Time.
• Western European Time (Portugal, UK).

As standard time (all year round)

The following is a list of places that use UTC as their standard time zone, but do not observe Daylight saving time:

West Africa

• Burkina Faso
• Côte d'Ivoire
• The Gambia
• Ghana
• Guinea
• Guinea-Bissau
• Liberia
• Mali
• Mauritania
• São Tomé and Príncipe
• Senegal
• Sierra Leone
• Togo
• Western Sahara

Atlantic Islands

• Greenland
  • northeastern
    • Danmarkshavn and surrounding area
• Iceland
• Saint Helena, Ascension Island and Tristan da Cunha (to UK)

Notes:

1. The westernmost point where UTC with no DST is applied is Bjargtangar, at the northwest peninsula of Iceland (24°32' W). Time used there is 1 hour and 38 minutes ahead of physical time. This is the greatest deviation from physical time for UTC with no DST.
2. The easternmost locale where UTC with no DST is applied is Bouvet Island, of Norwegian jurisdiction, at the South Atlantic Ocean (3°24' E).

As standard time (Northern Hemisphere winter only)

• Alderney
• Faroe Islands
• Guernsey
• Herm
• Ireland
• Isle of Man
• Jersey
• Portugal (with the exception of the Azores, which use UTC−01 with DST)
• Sark
• Spain (only Canary Islands; observes European Union DST rules)
• Morocco
• United Kingdom (GMT / BST)

Notes:

1. The westernmost point where UTC with DST is applied is El Hierro, Canary Islands, Spain (18°00' W). Time used there is 2 hours and 12 minutes ahead of physical time in the summer, making for the greatest discrepancy in the UTC time zone.
2. The easternmost settlement where UTC with DST is applied is Lowestoft in Suffolk, East Anglia, England (at just 1°45' E).

As daylight saving time (Northern Hemisphere summer only)

• Greenland - an eastern region around Ittoqqortoormiit (Scoresbysund)
• Portugal - the Azores only

As winter time

• Republic of Ireland Note that Ireland uses Irish Standard Time during the summer months and winter time during the winter months.

This is the reverse of the practice of most countries in the EU, but provides the same end results.
