ACK. Change looks sane to me and I trust @kfessel testing. Please confirm that the potential issue I pointed out inline is indeed not present before hitting merge.

+static inline uint32_t _now_sec(void)
There is a potential footgun with using both timestamps from ZTIMER_SEC and ZTIMER_MSEC, as both could be provided by different hardware. One could (or at least I can see myself doing so) assume that the timestamps can be converted to each other.
I don't see this incorrect assumption anywhere here in the code, but I'm not really familiar with it.
