There are two kinds of clocks. There is the clock that is always wrong, and that knows it is wrong, and glories in it; and there is the clock that is always right — except when you rely upon it, and then it is more wrong than you would think a clock could be in a civilized country.

Jerome K. Jerome (1859-1927) English writer, humorist [Jerome Klapka Jerome]

“Clocks,” Diary of a Pilgrimage, and Six Other Essays (1891)
