they try to make a clock which would last 10 000 of years or more with an
accuracy of 1 day in 20 000 years.
I would say a sundial could do that job and even more accrate I guess.
Perhaps even a new scale could be developed to indicate the millenium

Dear Diallists,
There were several mentions of the helical sundial in the BSS Bulletin some
time ago, but I don't have the references to hand.
As far as I understand it, it is arranged on a polar axis (like the gnomon
