/**
 * Binder APIs to communicate with the time detector service.

 * <p>Used to provide information to the Time Detector Service from other parts of the Android
 * system that have access to time-related signals, e.g. telephony. Over time, System APIs have
 * been added to support unbundled parts of the platform, e.g. SetUp Wizard.
 *
 * <p>Use the {@link android.app.timedetector.TimeDetector} (internal API) and
 * {@link android.app.time.TimeManager} (system API) classes rather than going through this Binder
 * interface directly. See {@link android.app.timedetector.TimeDetectorService} for more complete
