I am in the Azores islands, which is in the middle of the ocean (250 thousand inhabitants, plus other mid ocean archipelagos such as Iceland, Madeira, Canaries, Cabo Verde, Saint Helena, etc.), so does that mean I am shown a London UTC time for my location at Central Azores (Pico)? There is indeed a time zone for East-West Mid Atlantic ocean, which is Azores Time Zone. Azores TZ is 2 hours behind Madrid-Paris-Berlin-Warsaw and 1 hour behind Dublin and Lisbon and London as well (GMT-1)(UTC-1).

"Of course, if you open detail in the middle of the ocean, we use UTC, since there is no timezone."
