Changing that vector is one way to tilt the camera in some way. It's a 
3D vector that defaults to <0,1,0>.

It depends on what you want to acheive.

If you need an integer value that depends ONLY on the actual 
frame_number and is independent on the clock value, there is NO 
arithmetics to perform. It also assume that your animation is made to 
use only a fixed number of frames.

Your suggestion is only needed if, for some reason, you want to 
substitute frame_number for places suited for the clock variable.
