  spline settings to clock correspondence

Hello. How do these settings correspond to a clock moving from 0 - 1?

spline {
    cubic_spline
    -.25, <0,0,-1>
    0.00, <3,.1,-5>
    0.25, <0,.2,-8>
    0.50, <-3,.3,-5>
    0.75, <0,-.1,0>
    1.00, <2,.2,-5>
    1.25, <0,.1,-8>
   }
Is the entire range -.25 to 1.25 compressed into the 0 - 1 range of the
clock, or are the outer two values "guide points" for the spline?
Thanks,
D.
