This fails for me on both Fedora 42 and Ubuntu 22.04. I'm using Bash
shell on both machines.

This seems to work on both Fedora and Ubuntu:

     /usr/bin/time --verbose -- /usr/bin/ls

If time is located in a non-standard location (like /opt ?), then the
following should find it:

     $(command -v time) --verbose -- /usr/bin/ls

(I'm not sure why someone would update the time program, but I guess
it could happen).
