Hi Experts,

I have a client site with SBS 2008 and Terminal Server 2008 R2 running on Esxi 4.0.  The issues lies with the email time stamp.  

When the email is recieved, the time that it was sent is an hour  early eg The email below was sent at 7:05 (as per the subject line) however it is stamped as 6:05.

date Tue, Mar 1, 2011 at 6:05 AM
subject 7:05

We live in Perth Western Australia where there was daylight savings, now there is not - I have checked both servers and the they state they are in the correct time zone and are reporting the correct time.  They also correctly state that there is no daylight savings in this time zone.  I do not understand where this time stamp may be coming from.  

Any assistance on this one would be appreciated.

the timestamp could be coming from a firewall or the last hop to the internet.

clsbs.city-life.local is showing a timestamp of 803
this server has incorrect time or is in a different timezone.

there is also a difference in the UTC number. the first stamp shows utc of +9 and the later ones show utc of +8. unless the servers in a differnet time zone they should be the same.

OK - Thanks - Good spot - I can see this now you have pointed it out.  The next question is "why"

This server is in the correct time zone (Perth GMT +8) with the correct time.  

Where else can I look to determine where this issue may lie?

Can’t get the mobile email signature right?

Not having any luck when trying to create an email signature for mobile devices? Does the formatting keep messing up? Make sure you have great email signatures on all devices by using Exclaimer Cloud - Signatures for Office 365.

OK - the iron port is with the ISP.  This might take a while.....

Thanks for your assistance.  Will report back.

Time stamps are converted into the correct zone by sender and recipient machines.
So if the sender has the wrong settting, then nothing you do can fix that.

Your recipient simply takes the provided value (in GMT) and converts it for display.

The sender time zone is wrong. (should be +0800)
All your servers correctly stamp the message with +0800 as the mail moves from one to the other.

I am no longer thinking this is an ISP issue.....

Looking at the following:

Received: from CLSBS.city-life.local ([fe80::50ca:7523:20ab:2c4c]) by
 CLSBS.city-life.local ([fe80::50ca:7523:20ab:2c4c%13]) with mapi; Tue, 1 Mar
 2011 08:03:07 +0900

This looks to be a IPv6 address from the source server - Could there be somthing strange happening here as it appears to be where the time changes to +900?

There was apparently a second NIC used for testing at some stage that was still active.  Somehow the traffic was passing from one interface to the other and getting the time stamps mixed up on the way though.  

Disabling the second NIC resolved the issue.

I could not find a reason why there would be a time difference between the two NICs - Comments on this may be useful.  The issue is however resolved.
