script fields - using the date template shows relative dates in column view

This is different from system fields and datetime custom fields, which show the absolute date part only.

For now, as a workaround, you can use a custom template that takes advantage of the stuff in the Script Field binding. e.g.

#if ($value)
    <span title="$titleFormatter.format($value)"><time class="allow-future" datetime="$iso8601Formatter.format($value)">$dateFieldFormat.format($value)</time></span>
#end
