Demonstrate opposition to giving up GMT time to change to TAI

Hundreds of people gathered in Geneva to protest against the replacement vote of how to measure the current time by calculating new times. Currently, members of the International Telecommunication Union (ITU) are considering the fate of GMT.

>>>The fate of GMT is about to decide

In a conference 40 years ago, scientists decided to use GMT time based on International Coordinated Time (UTC), which is now commonly used as hours in atomic clocks because it is more accurate. with the rotation of the globe.

And the world now accepts UTC time frames based on GMT, average hours in Greenwich, this observatory is on the meridian of zero or the prime meridian in England.

However, the US proposed to switch to using the International Atomic Time Standard (TAI) instead of the current International Coordinated Time (UTC). International Atomic Time is the time measured by the oscillation of electromagnetic waves emitted by atoms or molecules moving from one energy level to another.

Time is calculated by the orbit of the earth around the sun. However, the earth is rotating at a slower rate due to many reasons, such as the tidal force, creating a difference between the UTC and TAI standards.

Therefore, an agreement is then made to synchronize two time standards by adding a 'leap second' whenever this distance is greater than 0.9 seconds. Therefore, the meeting in Geneva will decide whether to eliminate the 'leap second' mentioned above in order to work towards a new calculation.
