Date set incorrectly on tester!!!

Hi there,
Just new to this forum today but was wondering if anyone was able to advise me on my primetest 350. I had the date set wrong on the tester yesterday while carrying out tests for a client and only realised today when I uploaded the results!
Every test result is dated 23rd Aug 2012 instead of 29th. Is there any way of changing the date on the results? I've tried to on the preview page but it won't let me. Any advise would be appreciated thanks.
