Two standards, great confusion: Many watch manufacturers, such as Rolex , use the designation GMT for their models with two time zones. We explain the similarities and differences between the two designations and why the differentiation is crucial in many applications. If you are looking for a difference between UTC and GMT, you will notice it when comparing the time: Both clocks permanently show the same time. Nowadays, Greenwich Mean Time has the status of an ordinary time zone and does not enjoy any special status compared to the 37 other time zones currently used on the globe. This was not always the case: before the introduction of UTC on January 1, , Greenwich Mean Time served as an international reference time and was used as a standard in science, aviation and various other fields. The existence of such a reference time is indispensable: Uniform time information is essential not only in meteorology, but also for Internet-based applications, in space and even in Antarctica.

Instead, it's based on atomic clocks and is occasionally adjusted with leap seconds to remain in sync with the Earth's rotation. While GMT is affected by the minute shifts in the Earth's rotation, UTC ensures a more consistent, precise measurement, making it crucial for computing, navigation, weather forecasting, and international events. However, it's important to note that while GMT can be affected by Daylight Saving Time changes, UTC remains consistent year-round, without adjustments for seasonal time changes.

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. Therefore, the difference in time for other countries is indicated either by adding or subtracting hours from GMT time. The primary difference remains to be the fact that GMT is the denomination of a timezone, while UTC is the title of the time standard. The advancement of telecommunication technologies influenced the creation of an even more precise system of time identification. In particular, the concept of Coordinated Universal Time UTC was designed to provide a more accurate timekeeping system. Nevertheless, both of these time standards are widely used in the world for a similar purpose of time coordination.
