CNRA closed in 1931 but the broadcasts continued on CNRO when the station was acquired by the Canadian Radio Broadcasting Commission in 1933 and by the CBC in 1936 before going national in 1939. In Australia, many information-based radio stations broadcast time signals at the beginning of the hour, and a speaking clock service is also available. However, the VNG dedicated time signal service has been discontinued.
