Variable: org-html-datetime-formats
org-html-datetime-formats is a customizable variable defined in
ox-html.el.gz.
Value
("%F" . "%FT%T")
Documentation
Formats used for the timestamp added as metadata to the time HTML element.
This only has an effect when org-html-html5-fancy is enabled, but
does not affect how the timestamp is displayed. The format in CAR
represents the timestamp used for timestamps without a time component,
CDR the one for the full date and time. Note that the HTML standard
restricts what timestamp formats are considered valid for the datetime
attribute. See format-time-string for more information on its
components.
This variable was added, or its default value changed, in Org version
9.8.
