The ability to add some sort of countdown

This would problably be a very low priority feature, but while writing a thread on the Mythgard forum, I linked to something that won't happen for another 15-20 hours. I was thinking it would be cool to have some sort of text box, simmilar to the image and url ones, where you introduce a date and time (maybe even with the possibility of picking a time-zone), and there'd be a countdown telling you how many hours are left until the event happens. I doesn't even need to update itself constantly, only when you refresh the page.

This would also work amazingly with the calendar that was mentioned in another thread, if either ever get implemented.

I am not sure how many ppl would actually use this, so probably not worth dev time, but i could see it being implemented either in the text editor as a new feature (button) or as a bbcode with a parameter, that would simply create an element with a time you input and would start counting down from the moment you submit the post. Not sure if it could then live its own life or if stuff like editing a post would pause/disable/reset it, it would depend on the capabilities of what can be coded, which Flux will have to answer, but again, cool stuff, but not sure if worth the time spent on it.
