PURPOSE: To adjust a calendar clock easily and accurately while reducing the labor. CONSTITUTION: An error setting switch section 4 comprising a plurality of switches stores the values of set error (a) corresponding to the switching state. When an error measuring section 2 measures the error at a clock circuit section 1, a set error value (a) is determined from an error value (f) and delivered to an initial value operating/setting section 5. The initial value operating/setting section 5 calculates an initial value (b) for minimizing the error from the set value (a). The initial value (b) is delivered to a correction reference counter section 7 and held. When the initial value (b) is set, the correction reference counter section 7 counts the output (c) from an oscillator and delivers a reference pulse output (d). Consequently, corrected time information, i.e., a calendar clock output value (e), is delivered from a calendar counter section 8. |
