ABSTRACT:
A global timepiece provided with a counting circuit for electronically counting at least seconds, minutes, hours, days and months upon receipt of a signal from a pulse oscillator and particularly a control circuit for advancing a date from the last day of a given month to the first day of the following month according to a calendar, which comprises a date-counting circuit for counting a day by an advance pulse generated per day; a day-detecting circuit for detecting a count of "1" representing the first day of a calendar month which has been counted by the day-counting circuit; a circuit for setting the count made by said day-counting circuit at a "0" upon receipt of an output signal denoting a count of "1" which has been detected by the day-detecting circuit and also a time correction-instructing signal for backdating a date one day according to an instruction based on a time difference occurring between any two districts in indicating the count of "0" made by the day-counting circuit to represent the last day of each preceding month in the form of a specific notation.
