Short:Yes

Not as Short: The clock, by default goes from 0 to 1, interpolated over the
number of frames (i.e. clock value = frame_number*1/#frames) . If you have
cyclic animation turned on you would basically add 1 to the number of frames
(clock =  frame_number*1/(#frames+1)).  You can also override the defaults
for clock but setting Initial_Clock and Final_Clock in the .ini, the clock
variable is then interpolated between these two numbers in the same fasion.
If you use 3.5, there is the "frame_number" variable that will return the
actual frame number in your scene rather than "clock"

Hope that answers your question
