Post creation date

[eduherminio]

Summary

Support both creation and last update dates

Motivation

Having already the option of using date and last_modified_at in posts, I thought that (at least) when both are used at the same time, the former one could be used to show post creation date (as shown in the picture above), providing the authors with the option of displaying both.

Drawbacks

If keeping backwards compatibility is desired when only date is provided, date field would acquire two different meanings when it's alone (updated date) and when it lives together with last_modified_at (created date).
Otherwise, it could be a relevant (and undesired?) breaking change.

Possible implementation (includes/page__date.html)

{% if page.date and page.last_modified_at%}
  <p class="page__date"><strong><i class="fas fa-fw fa-calendar-alt" aria-hidden="true"></i> {{ site.data.ui-text[site.locale].created_date_label | default: "Created:" }}</strong> <time datetime="{{ page.date | date_to_xmlschema }}">{{ page.date | date: "%B %-d, %Y" }}</time></p>
{% elsif page.date %}
  <p class="page__date"><strong><i class="fas fa-fw fa-calendar-alt" aria-hidden="true"></i> {{ site.data.ui-text[site.locale].date_label | default: "Updated:" }}</strong> <time datetime="{{ page.date | date_to_xmlschema }}">{{ page.date | date: "%B %-d, %Y" }}</time></p>
{% endif %}
{% if page.last_modified_at %}
  <p class="page__date"><strong><i class="fas fa-fw fa-calendar-alt" aria-hidden="true"></i> {{ site.data.ui-text[site.locale].date_label | default: "Updated:" }}</strong> <time datetime="{{ page.last_modified_at | date: "%Y-%m-%d" }}">{{ page.last_modified_at | date: "%B %-d, %Y" }}</time></p>
{% endif %}

This would also require adding a created_date_label and associated translations.

Seems a bit clunky to me. The theme already supports post dates, which is the same thing as a “created” or published date.

Oh, wasn't aware of that, thanks!
In that case you can pretend this feature request never took place!
