get_date_link() needs integers..?

I would like for each post to show it’s date as a hyperlink to all posts on that date. get_date_link() sounds like a good bet, but it seems to need 3 integers, and I’m not sure the best way to get them…

btw, if i leave the parameters empty, i get an error about missing parameters instead of just the current date as this page says it should: http://wiki.ww.wp.xz.cn/?pagename=get_day_link

How get i get the 3 integers i need for get_day_link()?

seems like it would be a good idea for this function to default to the post date of the current article when called from within the loop…
