I'm confused by your position. If it's 7am on the clock behind me,
right now, then how (under the model proposed by the PEP) do I find
the datetime value where it will next be 7am on the clock?

I understand your point that "it's a calendar operation", but that
doesn't help me. I still don't know how you want me to *do* the
operation.

Whatever the outcome of this discussion, any PEP needs to explain how
to implement this operation, because at the moment, it's done with
+timedelta(days=1) and that won't be the case under the PEP. I'm not
trying to shoot down your proposal here, just trying to understand it.
