       #   correct for differences in clock settings between the browser's system and the
       #   server's.
       #
       #   The difference between clientTime and the time at which the ready() method
       #   starts executing is used to estimate latencies for page load and submission.
       #   Since this is an estimate, it is doubled.  The latency estimate + one minute
