LAST UPDATE

Last Update automatically displays when your page content was last updated. This makes it clear to everyone that your site is current and maintained—it’s not stuck in time. You don’t have to do anything extra—the date always updates itself with every change.

Last Update is an automatic modification timestamp bric: just add it to your page, and from then on, it will automatically display when the content was last updated.
There’s no need to manually edit the date—after every publish and even the smallest change, it stays up to date.
Visitors immediately see when something was changed, and you save time: no more fiddling with dates afterwards, no forgotten updates, and no incorrect information.
In short: set it up and forget it—after that, the bric handles the date, accurately and automatically.
