Opencart Extension Fix

We have an module/extension on our Opencart site. However the module is not working as it should or as we need it to. We need the code amending so that it fits our needs. Here is a link to the module : [login to view URL] The module displays a countdown on product pages. It tells you how many days hours and minutes you have before the delivery cut off (times set in admin) It also allows you to add some text above/below the counter. At present the counter should skip any days that you do not post items out (ie weekends) - this seems not to work. We would like the counter to work so that it displays the amount of time before the next cut off (bearing in mind we do not ship on saturdays or sundays), and the text underneath can dynamically display the day that the parcel would be delivered (based on next day delivery). This would be the next working day (exc saturday and sunday) So if customer is looking at our site 1 hour before cut off time on a friday, the counter would say : <text above set in admin> Order and select nextday delivery within the next: 1 hour 0 mins <text under set in admin>and receive your parcel on Monday ("Monday" would need to be dynamically inserted) the code is in place for this, it just needs tweaking to display the correct day. here is an example of a site that we would like it to work like : [login to view URL] I have added the file from the extension that i think controls the way the counter calculates and displays the information. any questions please ask.
