+Subject: [PATCH 088/134] Input: Use monotonic time for event time stamps.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+Since wall time can jump backwards, it cannot be used to determine if one
+event occured before another or for how long a key was pressed.
