 Modify the [`clock2.go`](./clock2.go) to accept a port number, and write a program `clockWall.go`, 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.
 
-On this lab, it's recommended to run your programs in 2 or more terminals; 1 for the `clock servers` and 1 or more for the `clients`.
