Generate trial balance

Hi Sappers!!

I need to generate opening trial balance as of 01/01/08 and closing trial balance as of 03/31/2008.

I have already tried a few reports and F.01/F.08. I do not see an option or key date that would generate opening and closing trial balance as of 01/01/08 and 03/31/08 respectively.

Would highly appreciate your inputs & time!
