As I was working on setting up an NTP Server for our local network, I wanted to make sure it was set up properly and working. To do so, I looked up for a way to do a simple thing like run a command con the cli and get information back. On windows you can use W32tm to do so and get a nice stripchart of the time offsets between your client and the NTP Server
Using w32tm you can easily query an NTP server and compare it with your local computer like so:
C:\>w32tm /stripchart /computer:time.windows.com
Tracking time.windows.com .
