/**
 * Manager that allows controlling and monitoring a device's time-of-day clock,
 * and that collects the device's time source objects.
 *
 *  - Must be instantiated in every device that has more than one time source
 *    object. In this context, a "time source object" is an instance of
 *    **OcaTimeSource** or a subclass of it.
 *
 *  - May be instantiated at most once in any device.
 *
 *  - If instantiated, object number must be 10.
 *
 *
 * Note: The clock value is accessible via Get and Set methods, but has not been
 * defined as a public property because its value is volatile and should not
 * cause property-change events. The current value of the **OcaTimeSource**
 * object designated by the **CurrentDeviceTimeSource** property of this Manager
 * is known as the **Device Time**. The property **TimeSources** was added in
 * version 2 of this class.
