+    // This can happen because when the input device is initially opened
+    // it has a default clock source of CLOCK_REALTIME.  Any input events
+    // enqueued right after the device is opened will have timestamps
+    // generated using CLOCK_REALTIME.  We later set the clock source
+    // to CLOCK_MONOTONIC but it is already too late.
+    //
+    // Invalid input event timestamps can result in ANRs, crashes and
+    // and other issues that are hard to track down.  We must not let them
+    // propagate through the system.
+    //
+    // Log a warning so that we notice the problem and recover gracefully.
