It is all important in that it is part of the total time that it takes to load your site.  If your connect time was consistently much longer, that would indicate a problem, probably with the server.

you mean if the connection time is longer than the time from the first byte to the last byte so its a problem withe the server? id it necessarily mean that its the hosting server? or it might be something else? for example images that are on different server?

does using cache can also help to the connection time?

Connection time is the time from the request to the first byte of the reponse.  In your graph, it is the yellow part.  It's not unusual for the first connection to a server to be a little bit longer and that can be true if make a connection to a different server(s) for part of the content.  Although I don't see the actual times on your graph, it looks pretty normal to me.  The first request has to get to the browser before it can make the request for the rest of the items on the page.

Oh, cache only helps After the first time something has been loaded in the browser.

It probably shouldn't affect Pingdom results because that would be misleading and you wouldn't see what a first-time visitor sees.  If you are able to use something in your browser instead of the Pingdom service, you would see that a regular page refresh often gets a '304 not changed' response which tell the browser to use the copy in it's cache.  In comparison to your chart above, when that happens the green would be virtually eliminated.
