Go to a proper newsgroup. Google.

<OT>
Read the man page for time, something like man time should work.

The manual page ("man time") will probably be helpful.

This is not a C question. If "man time" doesn't give you enough
information, try asking in comp.os.linux.questions.

We must do something. This is something. Therefore, we must do this.

I don't think anyone could explain you. You're just a fact of nature.

In Linux, we have `man` command for documenting commands (and
other things).

Don't you have anyone local you can work with for this sort
of thing? Face-to-face or class interaction is *much* more
effective than Usenet drip-feeds.
