Abstract
A synchronization signal output apparatus obtains time from a time server to synchronize an internal clock with the time of the time server, obtains an error between the time of the time server and time of the internal clock, and generate and output a synchronization signal. The apparatus sets, based on a magnitude of the error, an operation mode for generating and outputting the synchronization signal, and generates and outputs the synchronization signal at the timing that is based on the operation mode.
