My new project involves the requirement of manually setting a time of creation of nodes because they're looking into manually migrating parts of their old website into their new one. The date will mainly be used to sort the nodes, only 2 out of 6 content types will have the date printed in the frontend.
In D8 you can select between a date and timestamp field. Both output options seem to be the same. The only difference I noticed is the HTML output.
The timestamp output looks like this
<div class="field__item">Mon, 03/18/2019 - 18:00</div>
Date output looks like that
<time datetime="2019-03-18T18:00:17Z" class="datetime">Mon, 03/18/2019 - 18:00</time>
I found a documentation page for D7 on the matter: https://www.drupal.org/node/1455576 but I have the feeling that this information doesn't apply for those two field types in D8.
Which one should I choose for this purpose? And what's the difference in D8 between those two field types?
