## Summary
up_timer_gettime() and the Espressif RTC rdalarm handlers built a timespec
by calling a free-running microsecond timer twice — once for tv_sec (/
USEC_PER_SEC) and once for tv_nsec (% USEC_PER_SEC). The timer advances between
the two reads, so a cal boundary returns an inconsistent, possibly backwards
time.
Fixed in 4 places by reading the timer once into a local variable and
deriving both fields from that single snapshot:
drivers/timers/arch_timer.c : up_time
arch/xtensa/.../espressif/esp_rtc.c : esp_rtc_rdalarm
(esp_hr_timer_time_us)
arch/risc-v/.../espressif/esp_rtc.c : esp_rtus)
arch/risc-v/.../esp32c3-legacy/esp32c3_rtc.c : up_rtc_rdalarm
(rt_timer_time_us)
