Slughorn's age when taking Felix Felicis potion

I wonder if anyone has considered that the age at which Professor Slug took the Felix Felicis potion might be a clue?

At the bottom of page 187 (US edition) Slughorn says he took the potion at age 24 and at age 57.  The precision seems to call attention to itself.

The two occasions are approximately 28 years apart. Voldemort fell ca. 1981, and going by JKR's statement that Snape was "about 36" when the series opens (1991), his date of birth would be ca. 1955.  This would also be close to the birth year of the Maurauders,  who we know were in Snape's year in school.

The gap between the birth of Snape and the Maurauders and the fall of Voldemort roughtly corresponds to the gap between Slughorn's two uses of Felix Felicis.

Since we know from the memory of telling Riddle about horcruxes that Slughorne will lie, can it be possible that he lies when he says that the days he took Felix Felicis were normal, ordinary days?  Can the ages at which Slughorne took the potion be a clue?
