A Microsoft Exchange Server 2007 Hub server may incorrectly set the Sent time on an e-mail message.
This issue occurs when you change the time zone setting on the Exchange 2007 Hub server.
To resolve this problem, restart the Microsoft Exchange Transport service.
To prevent this behavior, stop the Microsoft Exchange Transport service, change the time zone on the Exchange 2007 Hub server, and then start the Microsoft Exchange Transport service.
Exchange 2007 uses the Microsoft .NET Framework DateTime.Now property to determine the current system time. Additionally, Exchange 2007 uses the .NET Framework TimeZone.CurrentTimeZone class to determine the current time zone. These variables are not updated when you change the time zone in Windows.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
