This seems like an example of not reading the manual and then blaming the tool.
The switch to dump what is executing is -d or --debug, the manpage has this listed in the list of flags you can pass, and they are even sorted alphabetically which means this is displayed near the top.
As for the time thing, it's not totally clear what you want, but you can probably just use the time command in the rule you want to measure. Most systems have an actual time command that is not a shell built-in at /usr/bin/time if for some reason the builtin doesn't work for this purpose.
