How Do I Change Lead / Account Created Date

Hi There,

I have leads which come in or convert over the weekend. So when I add them to Zoho or convert them to accounts they do no reflect the correct date. How can I change the created time and date of a lead or account?

This important as when our marketing guy wants to run reports he has to run everything Tuesday to Tuesday which is out of synch with everything else.

Can anyone help?

Thanks
