Greenwich Mean Time (GMT) is a timekeeping standard that establishes a time zone based on the mean solar time at the Royal Observatory in Greenwich, London. It serves as a reference point for time zones around the world, aiding in the calculation of time differences between regions. GMT is particularly significant in global contexts, where precise time coordination is crucial, such as in international logistics and supply chain management.

The significance of GMT extends beyond being just a time reference; it underpins many aspects of global operations, including scheduling, transportation, and communication across different time zones. It helps synchronize activities and reduce the complexities that arise from using local times, thereby making it easier to manage time-sensitive operations.

In contrast, the other options do not represent recognized global time standards. Global Merchant Time and Gross Market Time are not established terms in timekeeping or supply chain contexts, while General Mountain Time is a regional time zone in North America and doesn’t hold global significance like GMT. Therefore, Greenwich Mean Time is the correct term that aligns with established global practices.
