Received email off by 1 hour on Mac clients

Hello,

I have an interesting problem that I believe is DST related.

On our macs, the time on all email in their inboxes received since Sunday is off by one hour. The system time is correct and all calendar entries are displaying the correct time, however, any meetinging they create for this week appear to be the right time on their systems, on windows machines the meeting is 1 hour off.

This problem is only occurring on our Macs and this issue is not affecting any of our windows based systems.

The macs are running OS 10.4.10 with Notes client 6.5.6.

I would appreciate it if anyone could shed some light on why this is occurring.

Thanks.

Was the DST patch applied to the MAC systems?

Is there a patch for notes 6.5.6 mac? I searched IBM and the only patch I saw for DST was 6.5.5 or lower.
