About this clock
This is a GPS master clock you are free to use.
Time is displayed in UTC.
You are free to call the API
if you want to include it in your projects.
When calling the API, it automatically waits for the second to occur.
This means you can call it immediately again if you receive a successful response.

The connection to the clock is via USB (emulated serial).
