ENH: bring VTK's nightly start time from 11PM EDT to 10PM EDT, a little closer to ITK (9PM) and KWWidgets (9:30PM). Larger projects that incorporate multiple toolkits like VTK + ITK + KWW need more time to build, therefore need to start early; since they usually start by building VTK, this nightly start time of 11PM prevents any large dashboard to start before 11PM. Hopefully 10PM is reasonable for our west-coat friends.
