About UTC+12
UTC+12 is 12 hours ahead of Coordinated Universal Time: when it is noon UTC, it is 12:00 AM at UTC+12 the next day.
6 zones keep UTC+12 all year, covering 8 countries or territories: Russia, Fiji, Kiribati, Marshall Islands, Tuvalu, United States Minor Outlying Islands, Wallis and Futuna and Nauru.
1 zone uses it only in winter and moves to UTC+13 in summer, for example Auckland.
1 zone reaches it only in summer, from standard time UTC+11, for example Kingston. So the set of places on UTC+12 changes twice a year.
For a fixed offset in software, tzdata provides Etc/GMT-12; note the inverted sign of these POSIX-style names.
Abbreviations for UTC+12: NZST (New Zealand Standard Time).
UTC+12 and the sun
Across the large cities that keep UTC+12 all year, the clock runs 3 minutes ahead of mean solar time in Funafuti (179.2°) and 1425 minutes ahead of it in Mata-Utu (-176.2°). The offset’s own meridian is 180° east: the further a city lies from it, the further its clocks drift from the sun.
Neighbouring offsets: UTC+11 (Yuzhno-Sakhalinsk and Nouméa) and UTC+12:45.
