OK, this really confusing I know, I will try to keep it as simple as possible.

Since DST, Exchange has its time bollixed.
Symptoms:

Outlook 2000, 9.0.0.2711 and Exchange 5.5 SP4 in NT4 domain

Outbound mail from outlook to gmail sent at 1 am:
In Outlook Sent box time stamp is 1 am.
In gmail, time stamp is 2 am.

Inbound mail from gmail to Outlook sent at 1 am:
In Outlook inbox, in preview pane, time stamped 1 am (but set by local machine)
When opened, time stamped 12 am

Outlook Calendar
In Outlook new appt made for 1 am.
Once synced to remote calendar (phone), new appt is for 2 am.

Remote Calendar
In remote calendar (phone) new appt made for 1 am.
Once synced to Outlook new appt is for 12 am.

All times on all servers in domain including Exchange server are correct. Time on local machines (NT BDC and W2k Terminal Server) is correct.

Looked in Outlook at tools>options>calendar options>time zone. "adjust for daylight savings time"was checked and current time was correct. Different story on XP workstations-time off by 1 hour ahead, people were leaving work early. Corrected by unchecking the "automatically adjust clock for daylight saving changes". When logging on to a XP box that had not been corrected yet, as logon script was ran, the time changed from the correct time to an hour ahead. Something was overriding the correct time setting.

After the DST change I had to change the time on the PDC manually because it did not pick up the change on its own. Then I synced the BDCs and the Exchange Server with the PDC via net time. The PDC is also the time server for the domain. So today I went back to the PDC and the "adjust for daylight savings time" was checked. Then it dawned on me- for whatever reason the PDC did not correct itself for DST. I changed it manually. But since the "adjust for daylight savings time" was still checked, it was adding 1 hour to adjust for DST. Essentially, it was ignoring its own clock because it thought it had to arbitrarily adjust the time. I UNchecked it and I thought part of the problem solved (inbound but not outbound). But not really, after the weekend, back to the way it was.

Checked the Wireless Sync server- all PIM info is synced through this box. I had not unchecked "adjust for daylight savings time" on that clock. I unchecked it, no change. I rebooted the mail server and the PDC- no change. I checked the time on the firewall and made some adjustments-no change. Something is still arbitrarily subtracting 1 hour on the way in and adding 1 hour on the way out. Inbound mail run through MXLogic, they say alls well there.

I think I may go mad trying to fix this.

 
I'm surprised that this is the first year you've had problems since the DST change was initiated in 2007. Fixing the OS and Outlook clocks does not fix the Exchange clock. Read this thread Exchange 5.5 and Daylight Savings Time 2007 for more info and possible workarounds.

Cheers.
