With the globalisation and evolution of international relationships, the need for universal time identification has occurred. Especially, it was vital to have a standardised time zone for communication and military coordinations. The implementation of Greenwich Mean Time (GMT) was the first step to determine the time zone of other countries in rega...
The abbreviation of GMT stands for Greenwich Mean Time. The name derives from the place where the solar time was standardised for everyone: it was established at The Royal Observatory Greenwich. The term “mean”indicates the average time the clocks need to pass through the solar day. Also, considering that each day requires the same interval, the pe...
Origins of GMT
The history of GMT started with the decision of the International Meridian Conference in 1884 to establish the prime meridian which would denote the international standard of time. Considering that Great Britain was a developed marine nation, it used Greenwich Meridian to position own ships. Subsequently, Greenwich meridian was determined as zero degrees longitude, thus, the international standard time2. From that point, every nation used GMT to calculate the time in relation to this standard...
Emergence of UTC
Coordinated Universal Time was introduced as the more accurate replacement of GMT. In 1963, the concept of UTC was established as the primary international standard which would denote how other countries would regulate their time in relation to UTC3. The primary reason why UTC was considered to be a more accurate system was the fact that it used the rotation of Earth and atomic clocks for measurements. Moreover, to maintain the consistent time system, UTC does not observe Daylight Saving Time...
Zulu time denotes the Coordinated Universal Time in the 24-hours standard which is used in the military forces and aviation in particular. Namely, Zulu signifies the universal time standard for the pilots who fly in different time zones7. However, the term Zulu is just the synonym for UTC. The name of the time zone derived from the transmission art...
Consequently, the differences in the terminology of GMT and UTC still create confusion in international cooperation. Even though UTC was introduced as a more accurate time standard, the occurrence of the leap seconds demonstrated that even this system has minor flaws for the universal time synchronisation. One of the most common proposition is to a...

Current time zones. Coordinated Universal Time ( UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce.
