I've updated the graph at: http://www.megapathdsl.net/~hmurray/time-nuts/line/Calif-60Hz-2014-2015.pn g and added July-2015 at: http://www.megapathdsl.net/~hmurray/time-nuts/line/Calif-60Hz-2015-Jul.png July 19th shifted 15 seconds in one day! The shift is 25 seconds over July 17-19. -- These are my opinions. I hate spam.
