+ * These constants are used privately in Android to pass raw timestamps

+ * other way to transfer this information.  The evdev driver automatically
+ * timestamps all input events with the time they were posted and clobbers
+ * whatever information was passed in.
+ *
+ * For the purposes of this hack, the timestamp is specified in the
+ * CLOCK_MONOTONIC timebase and is split into two EV_MSC events specifying
+ * seconds and microseconds.
