I’m with Natural for some decades, so to place my question is somewhat painful.

Working on IBM z/OS, I have to tune a Batch Programm.

To get a baseline I determinted the Elpased time as usual:

```
at the begin
START. SETTIME
at the end
TD_ := *TIMD (START.)
with TD_ defined as
2 TD_ N 7 /*TIMD
R 2 TD_ /* BEGIN REDEFINE: TD_
3 TDHH_ N 2
3 TDMM_ N 2
3 TDSS_ N 2
3 TDTS_ N 1
```

Inspecting the log I see: “Elapsed time: 19:11:39.2”

Checking the JES2 Job Log

Job Start: 13.52.46 JOB39601 ---- THURSDAY, 09 JUL 2015 ----

Natural Step started 13.56.48

Natural Step terminated

09.08.28 JOB39601 ---- SATURDAY, 11 JUL 2015 ----

Based on this *TIMD() embezzled 24 hours.

I checked all available documentation, but I was unable to find any Limitation for *TIMD().

Is the a Maximum for *TIMD()?

Any Feedback is welcomed.
