Incorrect Calendar Date

[datahost]

Hi Everyone,


I have the following issue with my calendar.

when i create a task, I put my due date as 30/11/2007 and my start date as 27/11/2007, once I save it,

here is the result I return, I end up getting the wrong date.

================================================== =======
Subject: My Task 1 Status: Not Started
Due Date: 11/06/2009 01:00pm Accounts:
Start Date: 11/05/2009 01:00pm Contact:

The date created is correct, but due date and start date are incorrect.



Any idea?
