Date verification in HTML pages

Hello,
 
I have a question that has been in my mind for a while now. As a novice
web developer, I frequently rely on the web to provide me with technical
help/guide on various topics to help build web applications. During
these occasions I find it increasingly difficult to verify the date of
last modification of the web document returned by Google search. This is
very important as the end user needs a way to ensure that those web
pages providing content on issues that change over time are up to date.
 
Is there a credible way of verifying this date or if not could it be
enforced by the consortium in future HTML versions?
 
Thank you,
 
Regards,
VIGNESH
