For example, it is supposed to match the rate of the SI second on the geoid (which is roughly mean sea level). NIST's lab in Colorado is about a mile high, so they have to apply a general relativistic rate correction to their atomic clocks because of their gravitational potential. > so it should be good enough for most running code on the Internet. Except where that code needs UTC. Tony. -- f.anthony.n.finch <dot@xxxxxxxx> http://dotat.at/ Viking, North Utsire: Southerly or southeasterly 5 to 7, occasionally gale 8 in Viking.
