+static inline uint32_t _now_sec(void)

The drift pontential of msec vs sec is low enough for T1 and T2 application,

The problem left is one might uses SEC as some kind of RTC (which should not be done), combine that with DHCP and some NTP after getting the dhcp lease and you get a time scramble, this is a problem of the ztimer and not of this DHCP.
