This is now fixed:

  
https://git.savannah.gnu.org/cgit/shepherd.git/commit/?id=b36e97a730596dbf3c376f940150d5fd1f08ecf1

Let me know if you find something fishy.

The irony is that the work I did for <https://issues.guix.gnu.org/75622>
helped, but the one test that would have caught this issue was wrong: it
was looking at the wrong date when testing the CET->CEST change.

Setting #:wait-for-termination? #true would have mitigated this bug (it
wouldn’t have triggered).

Thanks,
Ludo’.
