One of my early mentors told me that he sees benefit about a month after the initial link is posted, and that the links seem to get stronger roughly 5-6 months in.  This seems to be true in my own analytics, though perhaps I'm reading into it a bit.  Some rough testing on my part seem to show that it takes about a month for a link to directly affect rankings though, certainly.

Alan is correct. To elaborate a bit, if you were to receive a link from the New York Times home page, google would see the link within an hour and your rankings could immediately benefit. The reason is nytimes.com has a PA of 99 which basically means it is one of the most important pages on the internet.

If you were to receive a link from a random page on an unknown site, or even a popular site but on a page which is deeply buried, the link may never be seen.

Crawlers move through the internet based on links. The amount of time for the link to your site being discovered is dependent upon how well  the page containing your link is linked from other pages.

It depends on when they are crawled, any think from a few hours to a few months, but useally a few weeks
