All timestamps say "43 Years Ago"

For some reason the timestamp is 0 (the UNIX timestamps start on Jan 1st, 1970).

Could you show us an example of a page, which exhibits this problem?

Hi guys,

This is a example of a page: https://blogfutebolclube.com.br/giggs-e-eleito-o-melhor-jogador-da-historia-da-premier-league/

I can post and edit. But the page is not updated with the comment, only if I manually refresh the browser. In Google Chrome, is the date 43 years ago. In Firefox, is the actual date.

What can it be? Thks guys!
