The most advanced time in the world is typically UTC+14:00.
This time zone, sometimes referred to as the "latest time zone" on Earth, means that clocks within it display the 'latest' time relative to all other time zones. UTC+14:00 extends as far as 30° east of the 180° longitude line. A notable example of a location using UTC+14:00 is parts of Kiribati, particularly the Line Islands. To accommodate this time zone, a significant fold exists in the International Date Line in the Pacific Ocean.
Therefore, if it's noon in London (UTC+0), it would be 2 a.m. the next day in locations observing UTC+14:00.
