A time ball is a now obsolete time signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators to verify their marine chronometers from their ships offshore. Accurate timekeeping is one means by which longitude can be determined at sea.

Famous quotes containing the words time and/or ball:
“Out-worn heart, in a time out-worn,
Come clear of the nets of wrong and right;
Laugh, heart, again in the grey twilight,
Sigh, heart, again in the dew of the morn.”
—William Butler Yeats (18651939)
“The world was a huge ball then, the universe a might harmony of ellipses, everything moved mysteriously, incalculable distances through the ether.
We used to feel the awe of the distant stars upon us. All that led to was the eighty-eight naval guns, ersatz, and the night air-raids over cities. A magnificent spectacle.
After the collapse of the socialist dream, I came to America.”
—John Dos Passos (18961970)
