When a Microsoft Exchange Server 2013 administrator creates a transport rule that uses the
ActivationDate or
ExpiryDate option, the Exchange Admin Center (EAC) should display the time as UTC. However, the time that is displayed is the local time of the client computer that runs the web browser and not UTC.
For example, even if you create a transport rule by specifying
ActivationDate in UTC time explicitly as in the following transport rule, you do not see this time displayed in the EAC:
new-transportrule TEST2 -subjectcontainswords "test" -RejectMessageEnhancedStatusCode "5.7.1" -RejectMessageReasonText "test" -activationdate "8/16/2014 9:00 +0:00"
