Ciao Renzo,

you have to find time/date module and publish there or use custom php code...

but there might be small problem, no place for that..

why do you think people need that, they do not have Time in their phones or laptops?

Usually newspaper have Date and Time on the Home page, and this is necessary to show what is published in a particular timestamp. If not the main function of journalism is out.

BBC

No date nor time.

Something else is date inside article.

Of course you can add it, but it's your task. It's custom work.
