JUNE 12. THE NEW ZEALAND GAZETTE. 1807

Notice to Mariners.—No. 30 of 1919.

Marine Department,
Wellington, N.Z., 10th June, 1919.

THE following Notices to Mariners, which have been received from the Hydrographic Office, London; the Hydrographic Office, Washington; the Presidency Port Officer, Madras; and the Department of Trade and Customs, Melbourne, are published for general information.

GEORGE ALLPORT,
Secretary.

GENERAL INFORMATION WITH REGARD TO WIRELESS TIME-SIGNALS.

THE accompanying list of wireless time-signals is intended to provide, in a form suitable to give all information required by the wireless operator, a complete and up-to-date list of all time-signals issued by wireless stations throughout the world. The details showing the method of transmission of any given time-signal, will be found in the “Admiralty List of Lights and Time-signals” or in the “International List of Radio Telegraph Stations” (The Berne List).

The times given in the 4th column of the list are expressed in the 4-figure notation employed for signalling during the war. The term “G.M.T.” here means the civil mean time of the meridian of Greenwich, with the day commencing at midnight and the hours reckoned from 00 to 23. Where two times are joined by a hyphen, the times denote respectively the beginning and end of the signal.

Most of the wireless time-signals at present transmitted are sent by means of an automatic arrangement operated by the pendulum of a chronometer situated at some observatory. In such cases absolute reliance may be placed upon the accuracy of the signal. There are, however, many stations in the world which are very suitably situated for transmitting time-signals to ships which could otherwise not receive them, where it would be difficult or impossible to establish an automatic system. In such cases “hand” signals may be provided; but in general these signals should not be trusted to be accurate within closer limits than about two seconds.

It is hoped that all wireless time-signals will eventually be standardized, so that there shall be only two kinds of signals transmitted, the automatic signals being all alike and quite distinctive from the hand signals. It is further expected that arrangements will be made for all time-signals to be transmitted at times so selected that a ship with only one wireless operator will be able to read them. A similar scheme for wireless weather bulletins is being evolved.

NOTE.—This notice will be subject to revision from time to time.
