I've got a timing mark scribed on one of my front mounts. It's easy to check the timing....but if it's off, you need to pull the distributor to adjust it anyway. The mark is nice to check the dynamic timing.
And I always set the static timing when I annually check the points. So, the mark & light is just a double check on the static timing & it assures me that the advance is working.
But if you just want to retard the timing a few degrees.....
Pull the distributor & loosen the timing plate lock screw and turn to advance or retard the timing (move the plate down to advance timing, up to retard). Remember, each one of those little hash marks represents about 4° of timing.
As you can see from the picture, this particular distributor needed to have the timing advanced by about 8° (two hash marks) to achieve the ¼” measurement for TDC.
