I think not, from etc/fstab:
/dev/ufs/rootfs    /     ufs     rw    1       1
[Pi3, 14.0-RELEASE-p6, / on microSD]

I just tried
rprohask@www:~ % date
Sun Jul  7 11:10:23 PDT 2024
rprohask@www:~ % ls -aul /
total 97
drwxr-xr-x  20 root wheel     512 Nov 10  2023 .
....

Trying
rprohask@www:~ % ls -acl
total 54956
drwxr-xr-x  8 rprohask rprohask     1024 Jul  7 11:10 .
gives a sensible answer for near-current time.

In sum, I was misusing ls -al / .

Thanks for writing!
