Finding time of query execution
One can find time of query execution in Jena from tdbquery using --time.
But does this --time include the plan generation time. If yes, is it
possible to find:
(plan generation time) and (time to retrieve the results after the plan
has been generated separately in Jena)?

You have sent two messages 8 hours apart and also asked the question on
http://answers.semanticweb.com/questions/25376/finding-time-of-query-execution
You may be in timezone +05:30; other are not. You are unlikely to get
answers on a Sunday night. Please be patient.

I need to know these query times as I am benchmarking Jena TDB against
postgreSQL. With postgresql I am able to separately retrieve the query
execution time after the plan has been generated by postgresql using
\timing. It would be great if Jena could also give me the time it takes to
retrieve the results after the plan has been generated separately by Jena
as that would help me take a one to one comparison.
I'll be really greatful to you for the guidance.
