Hi Friends,
It depends upon on how often Google crawls the website and web pages concerned and whether or not they determine the content worthwhile adding to their index. You can perform a search in Google to see if the web pages containing your links have been indexed and check the last cache date.

About 6 weeks on average, however Google does not include all your links in WMT.
