How to define clock generated by the other clock?

Hi, I have found the related info in QuartusII 7.1 handbook.

In fact, I have read it before, but I can't find any answer for my question above.

Just for the simple question above, could you answer directly, I'm a little confused.

The phase shift between CLKA & CLKB is based on fitting result, so they are unrelated clocks, right? And so I should cutting the path analysis between them?

I myself think that:

Thouth the phase shift between CLKA & CLKB is based on fitting result, but TimeQuest should also know the phase shift, so it should create tge generated clock automatically.

Thanks...
