The new coreutils-systemd's "uptime" command reports wrong values:

wrong, newer system:
raspi4c:~ # grep VERSION_ID /etc/os-release 
VERSION_ID="20230910"
raspi4c:~ # rpm -qf `which uptime`
coreutils-systemd-9.4-1.1.aarch64
raspi4c:~ # uptime
 06:28:33  up 4 days 21:40,  1 user,  load average: 0.16, 0.16, 0.11
raspi4c:~ # cat /proc/uptime
136079.24 225710.69

correct, older system:
raspi4a:~ # grep VERSION_ID /etc/os-release 
VERSION_ID="20230904"
raspi4a:~ # rpm -qf `which uptime`
coreutils-9.3-1.2.aarch64
raspi4a:~ # uptime
 06:28:51  up 1 day 13:48,  1 user,  load average: 0.09, 0.16, 0.12
raspi4a:~ # cat /proc/uptime 
136093.86 92370.61

These are raspberry pi4's which don't have a realtime clock, so the system
clock is wrong on boot.

The broken version does not consult the kernel:
