[112] The pendulum clock outperformed all other kinds of mechanical timekeepers to such an extent that these were usually refitted with a pendulum—a ...
Palindromic times can also be observed, e.g. 10:02:10 on 11/01/2001 (two minutes and ten seconds after 10 am on 11 January 2001 in parts of the world using month/day format) was the first fully palindromic time sequence of the twenty-first century.
