It may vary by OS version, but it has worked for me on every APFS system 
I've used through Sonoma (v14.) It shows (according to the man page) 
both local snapshots on the system disk and backups on external disks.

The 'diskutil apfs listSnapshots' command will show you which of those 
are APFS snapshot.

That's interesting. I didn't think that tmutil depended on the backup 
disk to list backups, but I guess I was wrong. Note that if you have a 
very full disk, there may be no local snashots extant because the OS 
cleans them up to make space as needed.
