Subject: 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.
