"The new expression for Greenwich Sidereal Time, GST, has to be in
agreement at the microarcsecond level, for one century."

That implies the old equation did not do that but it does not look like
it's causing my problem.
Related to earth rotation, a microarcsecond is 15 times smaller than a
microsecond.
I have a 57 seconds error. I still have an error somewhere unrelated to
using the old equation.
