Abstract

A digital electronic timepiece has normal time counting means and also a different time counting means, for example for local time in a different time zone or country. Electronic switching is provided for selectively displaying either the normal time or the different time. Each of the time counting means includes up-counting means and down-counting means so that under the control of corresponding setting means the time of either the normal time counting means or the different time counting means can be amended either upwardly or downwardly.
