What Does TDT Stand For?
TDT stands for Terrestrial Dynamic Time
TDT, or Terrestrial Dynamic Time, is a timekeeping system that accounts for the variations in the Earth's rotational dynamics. It is designed to provide a more accurate measure of time for astronomical observations and geophysical studies by incorporating factors such as the irregularities in Earth's rotation and gravitational influences. TDT serves as a crucial reference point in scientific research, enhancing the precision of time-related data in various fields, including astronomy, satellite navigation, and geodesy.
