weblog.lol: dt-published and datetime on <time> elements?

[bixfrankonis]

I've used <time> elements in my blog re-theme, but technically they are invalid because what's inside them isn't in a correct format. That would be ignored if my <time> elements could have a dt-published="" and/or datetime="" on them but those need to be in "machine readable" formats, so if someone is using a human-readable format on the existing {date} function, we'd need some additional function for this particular purpose, maybe something like {pubdate}?
