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.
