Depends on your shell. zsh will time each command in the pipeline
separately:
zsh> time ls | wc -l | wc -l
1
ls 0.00s user 0.04s system 54% cpu 0.071 total
wc -l 0.00s user 0.02s system 26% cpu 0.059 total
wc -l 0.00s user 0.01s system 14% cpu 0.053 total
Most other shells will time only the first command.
