Website Login/Logout time captured and record in excel

Is it possible to record time changes on website? what i mean is, on our office, we have an intranet website that we use to login and logout. I want to record the changes on the website so that i can track the time that I'm logged in and logged out as it is the basis on how we could get paid. Once I gather the time data, i would be able to create a table that i will use to add the time that im logged in. I appreciate your response excel masters. Thanks.strong text
