		* Current date and time, encoded as Unix time (in milliseconds).
		* Current date and time, encoded as Epoch time (in milliseconds).
		* This value denotes the number of milliseconds seconds that have
		* elapsed since 1/1/1970 UTC.
		*
		* Reading this value will give you the system’s time. This can be
		* useful to synchronize other vehicle systems (dash clock etc).
		* CarServices will write to this value to give VHAL the Android system's
		* time, if the VHAL supports this property. This can be useful to
		* synchronize other vehicle systems (dash clock etc) with Android's time.
		*
		* Writing this value will update the ‘ExternalTimeSuggestion’
		* value (if enabled). This value may be consumed by the “Time
		* Detector Service”, if other sources do not have a higher
		* priority. For information on how to adjust time source
		* priorities see Time Detector Service documentation.
		* AAOS writes to this property once during boot, and
		* will thereafter write only when some time-source changes are propagated.
		* AAOS will fill in VehiclePropValue.timestamp correctly.
		* Note that AAOS will not send updates for natural elapse of time.
		* int64Values[0] = provided Unix time (in milliseconds)
		*
		* Note that the property may take >0 ms to get propagated through the stack
		* and, having a timestamped property helps reduce any time drift. So,
		* for all writes to the property, the timestamp can be used to negate this
		* drift:
		* drift = elapsedTime - PropValue.timestamp
		* effectiveTime = PropValue.value.int64Values[0] + drift
