Daily Go Language Bible-Example: concurrent clock service exercises

Exercise 8.1: Modify Clock2 to support incoming parameters as port numbers, and then write a clockwall program that can communicate with multiple clock servers simultaneously, read time from multiple servers, and display the results of all services at once in a single table. Similar to the clock wall you see in some offices. If you have a geographically distributed server that can be used to run on different machines, or run multiple instances on the same machine, listen to different ports and p
