The sequence of both STCK and STCKE values is a unique, monotone ascending ones, so that even two successive STCK[E] instructions executed on the same CP yield such values. The programmable field serves a different purpose. It identifies which TOD clock in a multiclock SYSPLEX provided a particular STCKE value.
My difficulties with Paul Gilmartin's post continues. Appropriate correspondences with civil date-time values are sometimes very important indeed, but they are not just irrelevant but a gratuitous complication when one is dealing in elapsed-time intervals.
