"success in life .. a quarter hour before my time"

[Joel S. Berson]

The quotation "I owe my success in life to having always been a
quarter of an hour before my time" is attributed to "Nelson" (Admiral
Nelson, I presume).  See "Gas Industry", vol. 12, No. 4 (April,
1912), p. 209 [Google]; and the Evening Chronicle of Sept. 18, 1918
[Newspaper Archive via Google].

Is that attribution correct?

Joel
