Astronomical observatories find it useful to have clocks that keep sidereal time, but an astronomer will soon get into trouble if he decides when to go home on the basis of a sidereal clock, 6 because he will be home four minutes earlier every day, and after six months he will expect his dinner at breakrotated four minutes or fast time. Clocks that keep solar time are preferable for the regulation of practical affairs.

Sometimes the longitude is expressed other ways. in It may be written as the angle from the prime meridian to the local meridian, running counterclockwise (eastward) north pole. in the In this when the earth system, longitudes may example above, with a longitude is viewed from above the range to 360°, and the point of 30°W in the conventional system, would have a longitude of 330°. Longitude (westward) may when also be specified as the angle running clockwise in is viewed from above the north pole, the earth which case in the above example the longitude would be simply 30°.
