Record the value of System.currentTimeMillis() or System.nanoTime(). Run
your query. Subtract the recorded value from the current value of
System.currentTimeMillis() or System.nanoTime() to get the execution
time including how long the query took to transfer data from the server
to your client.

I'm not aware of a way to find out how long the query took to execute on
the server - excluding data transfer to the client - without using
EXPLAIN ANALYZE.
