Time is always calculated from which degree of longitude?

Explanation:
Time is anchored to the prime meridian, the 0-degree longitude that passes through Greenwich. This line serves as the reference point for universal time (UTC) and the system of time zones, where each hour corresponds to 15 degrees of longitude. So, the starting point for calculating time globally is 0 degrees, with time moving ahead to the east and behind to the west. The other longitudes are simply later reference lines or opposite points, not the baseline for time calculation.
