A brocken clock is exactly right twice a day, 24 hour period.

About a year ago, I watched a tv program about India.There is a great
big giant Sun Dial in India which is about a thousand years old, (more
or less, I forget just how old the guy said that Sun Dial is) that Sun
Dial is still accurate today within two seconds.

Sun Dials are fascinating.I like Sun Dials.
