Assunto: Estimate time without running the query

Dear all,
Only a doubt.
The Explain <query> command only estimates the cost of execution of a query, and does not estimate time for execution.
I would like know if exists some way to estimate the time, without running the query?

Best Regards
[]`s Neto
