Timing a Diesel Engine

I recieved a bad piece of advice that the timing was off on my fuel pump and therefore it should be adjusted.  With the right tools it can easily be returned to the correct timing position but timing a diesel is not a quick and easy thing unlike timing a gasser.  However, there is no need to ever have to adjust the timing on a diesel. When turbo charging you do not need to adjust the timing of a diesel and also unlike a gasser, altitude does not affect diesel timing.  Therefore you should never adjust the timing on a diesel.  The only time you need to is when you have removed the pump or if it has somehow been messed with.  If you do adjust your timing, unless you're right on, it's better to have your timing retarded (after the factory spec) versus before because you have a lesser risk of bottom end piston or bearing damage.
