Handling different TimeZone in EJB

Our EJB application which is browser based JApplet has to accomodate Internationalization(I18N). When ever we write the Date ,we write with time and with the insatnce of "GMT".
The sample code looks as below to write date.
<code>
_stmt.setTimestamp(1, new Timestamp(new java.util.Date().getTime()),Calendar.getInstance(TimeZone.getTimeZone("GMT")));
</code>
Though the user is sitting in a different TimeZone and inserting a record, the insert date will be always the server TimeZone which is different from the user's TimeZone.
Assuming that the serve is in USA and user is in Asia, the user is trying to insert a recod at 13th at 7PM. But that record will be written as 14th at 3AM in the server side due to diffeent TimeZone.
Now, the user tries to retrieve the same record immediately, he may not able to retrieve it because it is wriiten as a different day.
I would like to know how to solvw this different TimeZone issues?
Thanks
