Duration Time for a completed sql statement shows incorrectly as 00:00:00 (4238854)

When executing several select statements in the Editor by pressing F9, and Script Result Grouping is set to 'One Tab per Query', the 4 tabs show with the individual results, however the specified duration time is incorrectly shown.  

If the Command Panel is ticked to be displayed, the duration time for the first result/'Set 1' tab, shows the correct duration time, but all subsequent results/tabs, show the incorrect  duration time as 00:00:00.

In the 'Messages' tab, the durations show the actual results here but these are not reflected in the 'Duration Time' section in the Command Panel of the 'Result Sets' tab.

WORKAROUND:
View the results on the 'Messages' tab.

STATUS:
Waiting for fix in a future release of Toad for DB2.
