Electric clock
An electric clock is a clock that is powered by electricity, as opposed to a mechanical clock which is powered by a hanging weight or a mainspring. The term is often applied to the electrically powered mechanical clocks that were used before quartz clocks were introduced in the 1980s. The first experimental electric clocks were constructed around 1840, but they were not widely manufactured until mains electric power became available in the 1890s. In the 1930s the synchronous electric clock replaced mechanical clocks as the most widely used type of clock.

電子時鐘,由4個(或6個)七段顯示器構成,由左而右為「時」:「分」:「秒」,換成指針即為「短針、長針、秒針」,電子鐘的秒可有可無,並不會干擾到時間的辨識。
