EasyRGB defaults to "Daylight". Isn't that D65?

http://www.easyrgb.com/index.php?X=CALC

ColorMine uses these values:

#declare XYZWhiteReference = color <95.047,100.000,108.883>;
#declare XYZEpsilon = 0.008856;
#declare XYZKappa = 903.3;

Which illuminant does that correspond to? I have no clue, and assumed it 
was D65 as well.
