Sorry, I have to correct my earlier followup. This one is better:

Using the code above I got the same 'mistake'...

The inverse rotating works just fine:

//********begin pov code*********
    sphere {0,EARTH_RADIUS
                  texture {
                    radial
                    transform {ROT_TEXTURE}
                    texture_map {
                      [0.0  T_EARTH_DAY transform {ROT_TEXTURE inverse}]
                      [0.5  T_EARTH_DAY transform {ROT_TEXTURE inverse}] 
                      [0.52  T_EARTH_NIGHT transform {ROT_TEXTURE inverse}]
                      [0.98  T_EARTH_NIGHT transform {ROT_TEXTURE inverse}]
                      [1.0  T_EARTH_DAY transform {ROT_TEXTURE inverse}]
                    }
                 }
    }
//*********end pov code********

... but I feel there must be a simplier and more elegant solution to my
problem. Five times the same boring inverse transformation is definitely
too much writing...;-)
Thanks for your help!
