No meridians are called the time meridian. The Greenwich meridian which passes through Greenwich, London is called the prime meridian. From which time zones are calculated.
after meridian post meridian
Meridian lines can be used to measure time zones. They split Earth into different time zones.
There is no general meridian time. GMT stands for Greenwich Mean Time. It is at zero degrees longitude and all time zones are based on this.
it is necessary to adopt the local time of some central meridian because each degree of longitude differs by 4 minutes.so if we follow the time of each meridian it would be very difficult as the people in the same country will have different time and the people travelling around would have to change there time now and then.therefore a central meridian in the country is taken as the standard meridian and the whole country follows its time.

We begin to measure time at the prime meridian
after meridian post meridian
The standard meridian time for Europe is Greenwich Mean Time (GMT)
AM as in time means ANTE MERIDIAN PM means POST MERIDIAN

Prime meridian, International Date Line, time zones
AM = "Ante - Meridian"PM = "Post - Meridian""Ante" and "post" mean "before" and "after"."Meridian" is the imaginary line in the sky that runs north/south and passes directly over you.In the morning, the sun moves from the eastern horizon toward the meridian. At Noon, the sun crosses the meridian. In the afternoon, the sun has crossed the meridian and moves away from it toward the west.Morning is the time before the sun crosses the meridian = Ante-Meridian = AM.Afternoon and evening is the time after the sun crosses the meridian = Post-Meridian = PM.
There is no general meridian time. GMT stands for Greenwich Mean Time. It is at zero degrees longitude and all time zones are based on this.
In radio, AM stands for amplitude modulation.In TIME, it stands for Ante-Meridian (ref. the Prime meridian)Amplitude modulationAnte Meridian as in 11:00 AM (and PM is Post meridian)

Meridian is latin for midday so post meridian is the time after noon to jusst before midnight
