I'm repeating what I said above, but just send yourself an gmail with the hash in the Subject. Gmail will kindly timestamp it and provide a DKIM signature. Publish the mail headers gmail includes in the signature (which includes the timestamp and subject, but not the contents), the signature itself, and a link to hashed the document and you're done.
