There are many many seen (and unseen) components that make WP E-Signature UETA/ESIGN compliant. Among these many thing is the UTC time stamp.
A question we often receive is “The Time And Date Is Not Accurate. How Can I Change This?.”
UTC or GTM is “World Time.” We decided for consistency between documents and accuracy it would be best to implement UTC time instead of the local time zone.
Example: If a user is in California and another signer is in Japan the “local” sign time would differ for both he signer and the admin user. By using UTC time it is extremely clear (in court) as to what time and date the document was signed.
