Joe, One second in clock units is X'F4240000'. See the z/Architecture Principles of Operation for the format and contents of the CPU clock, figure 4-12 on page 4-47. The value for one second is in the chart under item 9 on page 4-52 here:
http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr011.pdf So right after you do STCK TIME then do this to get a time 90 seconds later (SEC90 is an 8 byte field, the same size as your TIME field): LLGF R14,=X'F4240000' M R14,=F'90' ST R14,SEC90 ST R15,SEC90+4 LG R14,TIME AG R14,SEC90 STG R14,TIME Then you can convert the binary TIME field using STCKCONV.
