Methods declared on the JadeWebService class and its subclasses that are marked as web service methods cannot have a return type of Any and cannot have parameters of type Any. (For details about specifying web service methods, see "webService Option" under "Method Options", in Chapter 1 of the Developer's Reference.)

Jade timestamp values use the local time zone. External web service consumers often expect Coordinated Universal Time (UTC) values and external web service providers often return UTC values. You may need to convert between UTC and local timestamp values, by using the localToUTCTime and utcToLocalTime methods of the TimeStamp primitive type.
