Hello Nathan,
To change the start time of the entire series of recurring appointments, double-click any recurring appointment, then click the Recurrence button in the invoked editor, and change any properties of the recurrence pattern. Since this dialog allows you to change properties of the recurrence pattern, this will be in effect for all recurring appointments in a series.
However, it's impossible to change the start time simply via a drag&drop operation. If you wish this feature to be added in the future, you're free to post a suggestion to our Support Center at http://www.devexpress.com/sc. Note also that this forum is peer-to-peer, and if you want to get an official 24-hour response from Developer Express Support Team, please contact them at http://www.devexpress.com/sc, and they'll certainly help you!
