Can you say more about the practical effect?  Is this causing a bug in
practice, is it a bug waiting to happen, or is it making the code
difficult to understand without any ill effect expected at run time?
(Any of those three is a valuable kind of feedback to offer --- I'm
just trying to figure out which one you mean.)

By the way, do you have core.trustctime set to true or false?
