         * The methodology is as such:
         * 1) Sort the status entries by their timestamp;
         * 2) Create a Map of each monitored service with a default
         *    PollStatus of unknown.
         * 3) Iterate through the sorted list of status entries until
         *    we hit a timestamp that is not within our time range or
         *    run out of entries.
         *    a) Along the way, update the status Map with the current
         *       entry's status, and calculate the current status.
         *    b) If the current timestamp is before the start time, store
         *       the current status so we can use it once we cross over
         *       into our time range and then continue.
         *    c) If the previous status is normal, then count up the number
         *       of milliseconds since the previous state change entry in
         *       the time range (or the beginning of the range if this is
         *       the first entry in within the time range), and add that
         *       a counter of "normal" millseconds.
         *    d) Finally, save the current date and status for later use.
         * 4) Perform the same computation in 3c, except count the number
         *    of milliseconds since the last state change entry (or the
         *    start time if there were no entries) and the end time, and add
         *    that to the counter of "normal" milliseconds.
         * 5) Divide the "normal" milliseconds counter by the total number
         *    of milliseconds in our time range and compute and return a
         *    percentage.
