Where in the World is The Classroom Clock?

My clock is being used by hundreds of teachers which is many more markers than are included on this map.  Until 2016 when I first placed it online to allow free downloads, I didn’t keep track of any sort of data.  All I could tell was a general GPS location.  I’ve recently started asking for more information because I thought it would be fun to know where teachers are located which would allow me to place a marker for their school on my map.
