Right, what you are measuring is the distance of travel the piston inside
the pump travels before TDC.  On turbo engines this is inscreased to give
more time for the fuel to burn in the prechamber.   Same as when you pull
your advance cable.  Cold diesel takes longer to burn, so it advances the
timing.
