For the SVC 99, the time as reported by the C library function clock(),
documented as
Approximates the processor time used by the program, since the beginning of an
implementation-defined time period that is related to the program invocation.
In other words, it is the CPU time used so far by the program. I suspect it
calls TIMEUSED under the covers.
For IEF032I
IEF032I STEP/BR14 /STOP 2019218.1435
CPU: 0 HR 00 MIN 00.00 SEC SRB: 0 HR 00 MIN 00.00 SEC
VIRT: 4K SYS: 252K EXT: 0K SYS: 10576K
ATB- REAL: 20K SLOTS: 0K
VIRT- ALLOC: 10M SHRD: 0M

What type of CPU time?
SMF30CPT - TCB?
SMF30CPS - SRB?
SMF30ISB – SRB CPU time for initiator work?
SMF30RCT – Region control task CPU time?
SMF30ICU_STEP_INIT – Initiator TCB time?
... etc ...
Please clarify your observation.
