Need to record the timing of each CALL step in a batch job...

I have a request to start tracking the time each step takes in a batch
process...

A manual process might be, to look through the job log for

*NONE Command 12/08/10 02:29:44.407088
QCLCLCPR QSYS 04CB FS001C HLTHPRDPGM 0242
Message . . . . : 34100 - CALL
PGM(PR002R) /* The CALL command
contains parameters */

*NONE Command 12/08/10 02:29:57.622312
QCLCLCPR QSYS 04CB FS001C HLTHPRDPGM 0251
Message . . . . : 34900 - CALL
PGM(PR051R) /* The CALL command
contains parameters */

Obviously, a manual process would not be my prefer method, given that
this needs to be done for multiple jobs and is not a one-time thing.
Additionally, I need the specifics of the parameters used during the
call.

My thoughts
1) Use command exit point(s) process/log the CALLs, but it appears
that CALL is one command for which the exit point is not envoked.
2) Replace CALL command with custom command whose CPP does the logging needed
3) DSPJOBLOG OUTPUT(*FILE) or maybe OUTPUT(*APIDFN) at the end of the
process, but *FILE at least doesn't provide the parameters used during
the call
4) List Job Log Messages (QMHLJOBL) API or Open List of Job Log
Messages (QGYOLJBL) API, guessing that niether of these will have the
parameter info I need either...

So it appear that my only option is option 2....

Does anybody have any thoughts, comments or alternatives?

Thanks!
