I am looking for a JS that is time sensitive and show next available delivery date according to the time of the day.

I am setting up a gift shop. When the customers browsing the pages, I want a JS that will show "available delivery date". For example: the JS will show "available delivery date" is Jan 26, 2010 if it is before 12:00EST, and will show "available delivery date" is Jan 27, 2010 if it is after 12:00EST.

Any help will be greatly appreciated.

Thanks.
