When I have several posts scheduled for later (which, by the way, is a killer feature), the dashboard lists when they'll go live by hours or days. While I appreciate a multiple-day delay not being listed as "57 hours", knowing the exact time would be helpful too. Just saying (e.g.) "3 days" covers a 24-hour span.
Maybe something in parentheses like:
* post title in 3 days (8/20/2007 20:01:56)
