Incremental Backup using "imsbackup"

Question

Dear every body,
I have a trouble and need the help from you, please help me in this case if you can, thanks.
I want to backup incrementally my mailboxes with "imsbackup" command. I have tested following below example but not succeeded:
1. I send/receive email between 2 users in my domain at 08:00AM.
2. I performed FULL backup the whole message store using imsbackup
3. At 09:00AM I send/receive another email between 2 users in my domain
4. I performed INCREMENTAL backup the whole message store using "imsbackup -d 20091217:083000....." but my backup file including the messages that I sent before 08:30AM
I have done this several times and get the same result.
Please kindly help me in this case, how can I use imsbackup to incrementally backup my mailboxes.
Any help and advices from you is appreciated.
Thanks all of you so much.

Hi Shane,
Thanks so much for your response.
The version of Messaging Server I am using is:
{color:#ff0000}bash-3.00# ./imsimta version
Sun Java(tm) System Messaging Server 7.0-3.01 64bit (built Dec 9 2008){color}
For your question:
Does this problem occur if you incrementally back up a single mailbox e.g.
./imsbackup -d 20091217:083000 ... user/<uid>/
My Answer is:
I have not performed above step yet because I want to backup mailboxes of all users.
For your question:
Is the time/timezone set correctly on the server?
My answer is:
Yes, of courses. I already set time/timezone correctly. I also checked the time stamp of newly created email in message store in server, their date are correct.
For your question:
Are you in daylight savings time i.e. you shift the imsbackup incremental time back-forward an hour and get the correct result?
My answer is:
I already tried many times but got the same result. For example, At{color:#ff0000} 9AM Dec 16th 2009{color} I sent an email. At{color:#ff0000} 9AM one day later (Dec 17th 2009){color} I sent another email. I performed incremental backup using{color:#ff0000} "./imsbackup -d 20091216:120000 -f- / > /email_backup/incremental.120000".{color}
The backup file I got contained the email I sent at 9AM Dec 16th.
Any advice on this ?
Anyway, thanks so much for your help. I am awaiting your response.
huynq.
