If, on the other hand, you are asking about the time-frame for listing ("inclusion") in the search engines, this also varies. But having an in-link from a valuable site usually serves to speed the process.
And if you are asking about how long it takes for your site to be listed high up in the search results, this can take weeks, months, or years, depending upon your design, content, and popularity amongst users.

You appear to be asking two things:
(1) How long does it take to get listed in the search engines?
Answer: It usually takes no more than 2-3 weeks after another site links to yours.
(2) How long does it take to get ranked well?
Does your site *deserve* to rank well? Is it obviously better than the sites that are already on the front page for your preferred search terms? If your site doesn't deserve to rank well, then it will probably *never* rank well.
To get your site to rank well, you must build a *useful*, *informative* site, with *lots* of *good* content. Brett's post 12 months to success in Google [webmasterworld.com] is old but as timely as ever.
If your site deserves to rank well, it's fair to say that it could take a year before it does.
