Re: [neonixie-l] US power grid frequency tests.

The mains "frequency", at least here in the U.S. is always being corrected for small variances that occur in the frequency during the day. Therefore the overall error is none over a years time. Clocks are therefore always accurate and never need resetting, unless of course there is a power failure, or when changing fron standard time to day light saving time, and vice versa. Ira

Personally, I do not understand what the benefit is of using the mains frequency. I always use a 4.194304MHz Quarz and so far all my clocks' accuracies are very satisfactory.

Glad I live off the grid and don't use the mains for timing my 
clocks. I won't notice a thing...

Of possible interest. A lot of my clocks use the grid as a reference.
