Quotation from: The Cruise of the Snark

Written by: Jack London

"But to-day is to-day," my literal mind insists. "I must correct
the sun for to-day and not for yesterday."

"Yet to-day is yesterday," urges my logical mind.

"That's all very well," my literal mind continues, "If I were in
Greenwich I might be in yesterday. Strange things happen in
Greenwich. But I know as sure as I am living that I am here, now,
in to-day, June 7, and that I took the sun here, now, to-day, June
7. Therefore, I must correct the sun here, now, to-day, June 7."
