I just added a whole number field formatted as timezone to the appointment entity and form. When I save any appointment, either a newly created one or update an old one I get an error from CRM saying a lot of things, but the main message is: "Crm Exception: Message: An unexpected error occurred., ErrorCode: -2147220970, InnerException: System.InvalidCastException: Unable to cast object of type 'Microsoft.Xrm.Sdk.OptionSetValue' to type 'System.IConvertible'."

This looks like a bug to me, it isn't happening in CRM 2011 for example, and I haven't tried it in CRM 2015 yet.

More digging show that there is a problem in 2015 too and that this might be isolated to appointment, it works on account, contact, task (to try an activity) and custom entities.
