Anyone know of a module similar to the one below but for Zen Cart? Did not see anything in plugins section, found one on oscommerce website which looks cool. It allows you to show an estimated ship date. It also lets you add holidays and days closed.

I would like something like this so during peak times when production gets backed up I can relate the delay to customers via module like this so they know before placing an order when it will be shipped.
