The term that describes the time at the Royal Observatory in Greenwich is Coordinated Universal Time (UTC). This is because UTC serves as the basis for civil timekeeping worldwide and is closely related to Greenwich Mean Time (GMT), which historically referred to the mean solar time at the Prime Meridian located at the Royal Observatory. Greenwich Mean Time and Coordinated Universal Time are often used interchangeably, even though UTC is more precise due to its reliance on atomic clocks and astronomical observations.

Other terms mentioned, such as Eastern Standard Time, British Summer Time, and Central European Time, refer to specific time zones or adjustments made for daylight saving time in various regions. These time zones are derived from UTC but are not the same as the time standard represented by UTC itself. Thus, while they relate to timekeeping, they do not specifically denote the time at the Royal Observatory in Greenwich like Coordinated Universal Time does.
