Update currentTime in dispatch loop
commit 312910b4e34215aaa50fc0c6092684d5878dc32f Author: Chase Douglas <chase.douglas@canonical.com> Date: Wed Apr 18 11:15:40 2012 -0700 Update currentTime in dispatch loop A request, like input device grabs, may check a request timestamp against currentTime. It is possible for currentTime to lag a previously sent event timestamp. If the client makes a request based on such an event timestamp, the request may fail the validity check against currentTime unless we always update the time before processing the request.
