      BUG 13454045 - 63524: BUG #35396 "ABNORMAL/IMPOSSIBLE/LARGE QUERY_TIME AND LOCK_TIME" HAPPENS A
      
      If a query's end time is before before its start time, the system clock has been turn back
      (daylight savings time etc.). When the system clock is changed, we can't tell for certain a
      given query was actually slow. We did not protect against logging such a query with a bogus
      execution time (resulting from end_time - start_time being negative), and possibly logging it
      even though it did not really take long to run.
      
      We now have a sanity check in place.
     @ sql/sql_parse.cc
        Make sure end time is not before start time - otherwise, we can be SURE the system clock
        was changed in between, but not by how much. In other words, when the clock is changed,
        we don't know how long a query ran, and whether it was slow.
