114421 Need web script simple project

I need a simple java, php or cgi script that will redate a time limited offer on my website page. Lets say the special coupon says If you Order by midnight 2/2/2007 you will receive a special bonus: Bonus1 Bonus2 ect Then at Midnight the coupon looks same but the date automatically changes to the new day and says 2/3/2007 and so on so it continiously rotates the date every day.
