Trivia of time zone

Trivia
In terms of the largest number of time zones, Russia is first, with eleven time zones, including Kaliningrad on the Baltic Sea. The United States is tied with Canada for second with six time zones. If the possessions of the United Kingdom, the United States and France are included it increases the number of time zones in each. Taking into account overseas territories and possessions, France is the largest, with over twelve time zones, the United States has nine time zones, and the United Kingdom has over eight time zones.
In terms of area, China is the largest country with only one time zone (UTC+8), although before the Chinese Civil War in 1949 China was separated into five time zones. The next largest country with only one time zone is India (UTC+5:30). China also has the widest spanning time zone.
Stations in Antarctica generally keep the time of their supply bases, thus both the Amundsen-Scott South Pole Station (U.S.) and McMurdo Station (U.S.) use New Zealand time (UTC+12 southern winter, UTC+13 southern summer).
The 27° latitude passes back and forth across time zones in South Asia. Pakistan: +5, India +5:30, Nepal +5:45, India (Sikkim) +5:30, China +8:00, Bhutan +6:00, India (Arunachal Pradesh) +5:30, Myanmar +6:30. This switching was more odd in 2002, when Pakistan enabled Daylight Saving Time. Thus from west to east, time zones were: +6:00, +5:30, +5:45, +5:30, +8:00, +6:00, +5:30 and +6:30.
Because the earliest and latest time zones are 26 hours apart, any given calendar date exists at some point on the globe for 50 hours. For example, April 11 begins in time zone UTC+14 at 10:00 UTC April 10, and ends in time zone UTC-12 at 12:00 UTC April 12.
There are numerous places where several time zones meet, for instance at the tri-country border of Finland, Norway and Russia.
There are about 39 time zones instead of 24 (as popularly believed). This is due to fractional hour offsets and zones with offsets larger than 12 hours near the International Date Line. Some micronations may use offsets that are not recognized by all authorities.
The largest time gap along a political border is the 3.5 hour gap along the border of China (UTC +8) and Afghanistan (UTC+4:30).
