APROPOS 'WORLD CLOCK'

The International Date Line is located in the middle of the Pacific Ocean on the 180th degree of longitude: As a result of the first circumnavigation of the world by Ferdinand Magellan from 1519 to 1522, the International Date Line was created, which has run exactly on the 180th degree of longitude since an international agreement in 1884. If you cross it in an easterly direction, you end up in the past day (yesterday), whereas if you cross it in a westerly direction, you end up in the next day (tomorrow). Starting from Greenwich, a district of London, the globe was divided into 24 time zones, counting from the prime meridian, which begins at Greenwich Observatory. Every clock enthusiast should demonstratively cross the brass band embedded in the sidewalk once.

Each time zone is one hour. 24 time zones, of course, because the day has 24 hours and the earth rotates on its axis once in a day. Because of these different time zones, not all children born the same moment have the same birth time on their birth certificate. So if a baby saw the light of day in Basel on March 1, 2022 at 8.43 a.m., a child born at the same time in Sydney (Australia) would be recorded at 6.43 p.m. However, if a woman gave birth to her child in Los Angeles (USA) at the same time, its date of birth would be February 28, 2022 at 11.43 pm. Different birth times, different birthdays and even different birth years.
