how to get timing for a single execution of a specific SQL

Hi. I am running oracle version 11.2.0.4 and working on researching some application timeouts from the DB perspective. I have turned on database tracing with level 12 and that generated multiple tracefiles while the timeouts have been ocurring. When I run a tkprof

tkprof p_ora_56659.trc p_ora_56659.log explain=/sys=no waits=yes aggregate=no

it created an output file which included the following data for one of the problematic SQLs

call     count       cpu    elapsed       disk      query    current        rows

------- ------  -------- ---------- ---------- ---------- ----------  ----------

Parse        7      0.00       0.00          0          0          0           0

Execute   1547      0.02       0.02          0          0          0           0

Fetch    29376      0.67       0.70          0      29376          0      287576

------- ------  -------- ---------- ---------- ---------- ----------  ----------

total    30930      0.69       0.73          0      29376          0      287576

So it looks like 1547 executions which overall took 0.73 sec. What I am looking for however is the time of each of the 1547 executions. I was expecting to see 1547 EXEC lines for this particular SQL in the trace files, but only found one line.
