Coordinated Universal Time
Usage examples
  • Coordinated Universal Time is the time zone "0" from which all other time zones around the world are then calculated. It is similar to Greenwich Mean Time (GMT), but unlike this time, it is not based on the time of rotation of the Earth, but on measurements made by atomic clocks that are most accurate and above all more stable over time.
