As far as I can see: the EPSG database has Coordinate Frame Rotation
values in microradian, see:
If one reverts the sign, converts to arc seconds and prints the result
with "%.15g" format, one ends up with what the values are now, e.g.
rX = 1.9342 microradian => -0.398957388243134 arc seconds
The result does indeed look a bit like having some overprecision.
