Here are the procedures to an NTP server on you network: on the Unix derived mac you use “ntdate -q <server name or ip>”, but on windows you use “w32tm /stripchart /computer:<server name or ip>”.
Now I started the w32tm /stripchart /computer:10.10.10.50 in power shell on my dell notebook and it started to running away with the message to use “Ctrl-Break” to stop. Here’s where it gets fun, the FN extra keys labeled in small orange letters don’t have anything called “Break”, it took me a few minutes to do Ctrl-FN-Insert to stop this. (The insert key is labeled with small orange letters as “Pause”.)
