Tatjana Azundris Nuernberg 1c1bcb1c80 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.
