Indeed. And you got only a partial answer. It's in the DS9TIME field of the
F9 DSCB, but no advice on interfaces to it. I suppose there's always EXCP.
Looking for more information, I found:
http://publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=%2Fcom.ibm.zos.r12.adru000%2Fow19618.htm
2. For a preallocated target that has F8/F9 DSCBs, the F9 DSCB field DS9CREAT
is set ON, and is being scratched and reallocated, these patch byte settings
will not be honored. These types of data sets have a field in the F9 DSCB which
corresponds to the number of milliseconds past midnight in which the data set
was created (DS9TIME). In order for the DS9TIME to be usable, the creation date
and the time past midnight of the preallocated target will be preserved as its
value prior to scratching.
Microseconds? Milliseconds? Who cares? They're both too small to be much
concerned with.
