3.1.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that specified in this document.
This protocol is used to retrieve time zone information from the server to provide client applications with the information necessary to translate server time information to the time zones that the client application requires.
The client is not required to maintain the time zones used by the server; instead the client can use this protocol to request time zone information as necessary.
