I`m having a little trouble displaying future dates...

I`m woriking with a db of articles for a news-site, and the reporters want to be able to manipulate the dates to store as todays-date + 1-7 day(s). This way they can write articles in the weekend and holidays, and they won`t be published until it`s a normal work-day again... They also want the time to be exactly 07:00:00. At first i used ADD_DATE(NOW(), INTERVAL 1 DAY), but this ment that if they wrote the article on an saturday evening at, say 18:35, the article wasn`t published until 18:35 in the evening (on the desired date) In the form where they write their articles and select the date, I have now tried this: <SELECT name=\"date\"> <option value=\"DATE_ADD(CURRENT_DATE(), INTERVAL 1 DAY)\">Todays date + 1 day</option> etc through 7... And in the input script i had: {$date = "$date 07:00:00" ;} before I toss it into the MySQL table. But it only stores as 0000-00-00 00:00:00. I suppose it has something to do with my format. How can I solve this?
