"The clock is running. Make the most of today. Time waits for no man.
Yesterday is history. Tomorrow is a mystery. Today is a gift. That's why it is called the present."
In the 1902 book, "Sun Dials and Roses of Yesterday: Garden Delights..." by Alice Morse Earle, it is noted that the words "Time Waits for No Man" is a play on words or punning device of "gnomon" that has been used on sun dials. A gnomon is a pointer on a sun dial. Somewhere along the way came the full quote which has been truncated by some to your version.
And it was in the Kngfu Panda movie.
