10B

Explanation
Timer supervision found an error on the input parameters
for the TIME macro.

System action
The system takes an SVC dump.

System programmer response
Use the program status word (PSW)
address in the CLK entry to identify the caller. Do one of the following: If the caller is provided by the installation, check the parameters
on the TIME macro.  If MIC or STCK was specified, the area specified
by the address must have the caller's storage protect key.
If the caller is provided by IBM®,
search problem reporting data bases for a fix for the problem.
If the PSW does not contain the caller's address, contact the IBM Support Center.
