A STCK value, as Bob Wright mentioned, is considered "absolute time". Absolute to UTC: apply leap seconds Absolute to Local: apply leap seconds and time zone offset
UtcTime = StckTimeStamp - CVTLSO LocalTime = StckTimeStamp + CVTLDTO - CVTLSO Assuming addressability to the CVT, and assuming z/Architecture, LG R1,StckTimeStamp ALG R1,CVTLDTO SLG R1,CVTLSO STG R1,LocalTime Without z/Architecture, 8-byte arithmetic can be accomplished using register pairs, accounting for carry and borrow.
