Hummingbird Clock

do you know if a school wanted to test it if they would or not? I couldn't find anything recent for contact details other than submitting a request in.


As well as being freaked out, I don't quite 'get it'.
A bit like dendrochronology. Like using tree rings to determine an historical time period, you can now use the a record of the variation of the mains frequency detectable in audio or video recordings, to determine the date/time the recording was made.
It really should have a name.
Anyone have a name for this 'ology'?
