Change date label on listing page from '1970'

[vogias]

When repository date is not determined, the label will be 'N/A' with a explanation tooltip instead of '1970' value

[vogias]

I will implement it

During the virtual meeting we decided not to do this change, AFAIK

To do it properly we need a "N/A date" at all levels included the faceted search form. Now you choose 1970 in the faceted search and in the outcome you will read "N/A" but any other year will have a different behaviour

@vgoya What do you think of a solution like the following?

[vgoya]

Much better solution, yes.

This is already implemented on 1.0.2 Closing issue
