Latest commit 2170ca4 Oct 1, 2015 @meisterluk meisterluk committed with meisterluk Use <time> instead of <abbr>.
The pubdate given is in no way an abbreviation. Hence the semantics of
<abbr> do not justify its usage in this context.

<time> was introduced in HTML5. It's datetime attribute can override the
textContent. Anyway it specifies a date+time of a given event.

Originally the pubdate attribute was meant to annotate that the
publication date of the closest section unit is specified, but this was
dropped and is not part of the official specification.
