Exercise 8.1 (P222)

Modify clock2 to accept a port number, and write a program, clockwall, that acts as a client of several clock servers at once, reading the times from each one and displaying the results in a table, akin to the wall of clocks seen in some business offices. If you have access to geographically distributed computers, run instances remotely; otherwise run local instances on different ports with fake time zones.

    $ TZ=US/Eastern    ./clock2 -port 8010 &
    $ TZ=Asia/Tokyo    ./clock2 -port 8020 &
    $ TZ=Europe/London ./clock2 -port 8030 &
    $ clockwall NewYork=localhost:8010 London=localhost:8020 Tokyo=localhost:8030
