I hope that I am missing something.
The STCKE instruction, an unprivileged one, yields a 16-byte value at
a nominated storage location.
The difference between two such values, trimmed of their two rightmost
bytes (the programmable field), yields an elapsed time.
This value can then be formatted in a variety of ways.
No use of the TIME macro need or should figure in this operation. Any
leap-second corrections would, for example, be washed out by the
subtraction:
(T + L) - (t + L) = T + L - t - L = T - t.
Why all this pother?

I thought about using the STCKE instruction as you suggest.
But it occurred to me using TIME and STCKCONV provides a
relatively easy way to get date and time into easily
formatted versions without going through the machinations
myself of converting TOD clock values.
Leap seconds are of no interest here, I just wanted to
display start and end date and time and then calculate
the difference as an elapsed time. The approach I ended
up using works fine for my needs.
