By your literal example, you would be getting a timing that includes
the execution of "ls".  Is that really what you want?

Assuming not, probably the closest you can get is to declare

    float SECONDS

and then print $SECONDS at the end of your precmd function, and at the
beginning of the zle-line-init widget call "zle -M $SECONDS".

However, I don't know how to explain in detail how to accomplish that
because you mention using plugins and I have no way to know whether
those plugins have co-opted precmd or zle-line-init for other uses.

If you really do want to include the execution time of "ls", then
print $SECONDS at the end of preexec instead of at the end of precmd.

Just to demonstrate, here's the output from precmd/zle-line-init with
an otherwise virgin "zsh -f" on my desktop:
