What is a visit is it the search time or the time I am on the page?
I know I have searched for things that seem to take a long time (when I am in a rush) but the results page show my search took e.g. 0.22 seconds when really the page may have loaded slow or I had to reload the page taking maybe 30 seconds or Google Instant is being annoying.
That's the time Google spent preparing the result page for your search (finding and sorting the matching results). Actual time between you making a search and seeing that page involves much more than that computation, such as network latency and time to transfer the HTML.
Did you read this submission? It's not about Google search results. It's about how the time-on-site metric in Google Analytics is computed.
A visit is the time you are on the page (that is, not including any time you spent on Google or your favorite social network finding a link to the page). Which makes sense - the length of a visit to a physical place doesn't count the time you spend looking up its address while you're at somewhere else entirely.
