[Krang-devel] date formatting

[Perrin H. <pe...@el...>]

Formatting cover_date for use in both my article template and my
category template currently requires me to override fill_template and
add an identical strftime in two places.  I was thinking about putting
this in one spot, maybe by separating the strftime call into a method
with a default in Krang::ElementClass and then overriding it in a
subclass that I make all of my elements inherit from.  Does that sound
worth it, or over-engineered?  There's probably a way to do this with
HTML::Template::Expr instead, which might be better, but I didn't see
strftime in the docs.
