[PATCH] 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.
