Abstract

A method, system, and software associated with a client-server communication architecture in which there is a server and one or more clients. A client of the one or more clients communicates the client'"'"'s time zone value to the server over a communication path and during a communication session between the client and the server. The time-zone value is so communicated through options negotiations between the client and the server. The negotiated time-zone value is stored in a storage area of a computer system that includes the server.

Claims

1. A client-server communication method, comprising:

receiving, by a server from a client over a communication path and during a communication session between the client and the server, a negotiated time-zone value that identifies a time zone of the client, wherein receiving the negotiated time-zone value includes receiving the negotiated time-zone value in a storage area of a computer system that includes the server,

embedding the negotiated time-zone value into a generic root of a name of a logical subsystem of the server;

during the session, executing on the server an application initiated by the client or initiated from within the computer system, wherein executing the application includes;

retrieving the time-zone value by parsing the name of the logical subsystem to determine the negotiated time-zone value from the generic root; and

determining whether to take an action relating to the client based on whether a condition involving the retrieved time-zone value is satisfied, wherein to take an action relating to the client comprises at least one of;

to communicate a message to the client and to terminate the session.

2. The method of claim 1, wherein executing the application was initiated from within the computer system.

3. The method of claim 1, wherein executing the application was initiated by the client.

4. The method of claim 1, wherein the method comprises:

routing the session to the logical subsystem.

5. The method of claim 1, wherein receiving the negotiated time-zone value includes receiving the negotiated time-zone value through use of an environment variable as a negotiated option.

6. The method of claim 1, wherein the client is a Telnet client, and wherein the server is a Telnet server.

7. The method of claim 1, wherein the communication path includes a TCP/IP network, and wherein the client is directly connected to the server via the TCP/IP network while the time-zone value is negotiated between the client and the server.
