[time-nuts] Historical frequency data of UK grid

[Dr. David Kirkby (Kirkby Microwave Ltd)]

Unlike the USA, the UK has just one grid. Someone pointed this out to me,
which looks an interesting visual display

but there are links to the raw historical data, which includes frequency. I
have not looked into how much data is available, but it might interest
some, especially if you have made your own frequency measurements.
