This is where the time dilation effect comes in.

Simply put velocity (V) = change in distance (delta d)
diveded by time taken(delta t)

If the sum of two velocities is greater than the speed of light
then a limit is hit due this impossibility. The equation no
longer balances i.e. v != delta d / delta t 
The change in distance is known and therefore the time taken
must vary in order to balance the equation. That is why 
two objects travelling at great relative (to each other) speeds
seem to experience different 'times'.
