Unable to interact with hardware clock on Turris Omnia
I am running TurrisOS 5.1.1. I noticed my hardware clock is several days out of date, causing a lot of operations to fail at boot until system time is updated by NTP. The issue is I cannot update the hardware clock and the value I can read with busybox hwclock is always the same.

open("/dev/rtc0", O_WRONLY|O_LARGEFILE) = 3
clock_gettime(CLOCK_REALTIME, {tv_sec=1601045609, tv_nsec=617766075}) = 0
open("/etc/TZ", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_CLOEXEC) = -1 ENOENT (No such file or directory)
ioctl(3, RTC_SET_TIME, {tm_sec=29, tm_min=53, tm_hour=16, tm_mday=25, tm_mon=8, tm_year=120, ...}) = 0
exit_group(0) = ?
+++ exited with 0 +++With util-linux hwclock, I can't even access /dev/rtc0:
root@turris:~# /usr/sbin/hwclock -r -v
hwclock from util-linux 2.34

Using the rtc interface to the clock.
Assuming hardware clock is kept in UTC time.
