Interface ClockService

public interface ClockService

The ClockService is used to configure how to sych the hardware clock with a remote network service. The service reports when the clock has been synchronized last and raises an event when it is synchronized. The ClockService is configurable to determine how the clock synchronization should happen. By default, the ClockService can be configured to set the time through a Java NTP Client. It can also be extended to synchronize the clock through a native Linux NTPD service, using the clock acquired from a GPS signal provided by the Position Service, or through the a cellular carrier.
