-     * 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.

+     * Note that the property may take >0 ms to get propagated through the stack

+     * for all writes to the property, the timestamp can be used to negate this

+     *     effectiveTime = PropValue.value.int64Values[0] + diff
+     *
+     * Aside, this property could have been better named ANDROID_EPOCH_TIME, but it
+     * continues to be called EPOCH_TIME for legacy reasons. We will try to fix
+     * this naming discrepancy when we migrate to AIDL.
