Java EE (Java Enterprise Edition) General Discussion

I am downloading the message using IMAP. It is working fine and downloaded the message. I want to download the message from server by the last mail downloaded time.(Which i have maintained in the local system)

code is,

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy");
Date temprecvDate = simpleDateFormat.parse("Sun Feb 22 23:00:00 CST 2009");
ReceivedDateTerm recvDateTerm = new ReceivedDateTerm(ReceivedDateTerm.GT, temprecvDate);
messages = inboxFolder.search(term);
..
..
..

The following debug message we got

A4 OK [READ-ONLY] EXAMINE completed.
A5 SEARCH SINCE 22-Feb-2009 ALL
* SEARCH 24379 24380 ......
....

It seems to be search is disregarding the time in the search. How can we achieve this? I want to retrieving the message based on time.

thanks in advance
