actionscript 3 - Date issue in Client(Flex) and Serverside(JAVA) issue -

I have a repeat in Flex applications.

While Flex apple (28/09/2010 10:00 AM) in the form of a string, the date object applicant is cobnverted on the date in the side and displays the results.

But I installed the server in another location (ex: - USA). Now I am passing the date from India (28/09/2010 10:00 AM) but the date is different in the United States is. How do I change the date? Should there be a conversion in a client side or server side? What date does the server know on the date given by the client?

Thanks, Sun
