Prime Meridian
The Prime Meridian is the longitude which has been designated as a zero line. On the claimsmap version 8.0.1, the longitudes were introduced, which determined the prime meridian. From this line are the longitudes measured at 0° to 180° east and to 180° west. Both the Pallisican Scientific Standard Calendar and the Coordinated Micras Time count their time zones from the prime meridian.
