That was true in the USA as well, but with grids getting larger and the
number and types of sources increasing the compensation was getting
harder and harder to do while maintaining stbility.  Since the grid is
no longer an important source of time they relaxed the limit on
accummulated phase error.  Slashdot was full of cries of doom.
