Fix bugs in Reminder Application

I have a custom built reminder application. The user enters a string such as "meeting with bob next tuesday at 4pm" and the script recognizes the date, time and event and setups an email reminder for the user. The script currently has a number of bugs which cause it to not recognize every date correctly. Your task will be to fix these bugs to ensure that the script correctly recognizes the dates and times from various strings input by the user. There are also a couple of UI bugs (text displaying at the wrong time) Please PM me for the apps URL as well as the list of bugs I have discovered. This is a custom built app and is quite complex so strong PHP, Ajax and MySQL skills are essential. Work needs to be completed asap. If work is done to a high standard and cheaply ongoing work will be offered on this startup.
