I went to my SSO as well, and after I realized they only take check or money order I came back to get a check. Got the idea of just calling my old employers, got all the dates I needed, and more precise than the SSO one. The girl that helped me there said that it was only years or some such, and not month/days. I got the exact dates from my last employer, and then I called a company that handed payroll for another one and got the info from them. So you can also just make some phone calls and save yourself 30 bucks too.
