Document Type and Number:
Japanese Patent JP7006090
Kind Code:
B2
Abstract:
To provide a satellite radio wave receiver, an electronic timepiece, a date-time information acquisition control method and a program with which it is possible to acquire accurate date-time information more efficiently.SOLUTION: The satellite radio wave receiver comprises a receiving unit for receiving a transmitted radio wave of a positioning satellite and a control unit. The control unit determines whether or not execution information is included in a transmitted radio wave that is received in positioning operation performed after first reference timing before adjustable timing, with execution information of leap second adjustment at latest adjustable timing at which leap second adjustment is executable being not acquired as an information acquisition condition. And when the information acquisition condition is satisfied, the control unit performs first acquisition operation to acquire the execution information and adjusting the counted current date-time on the basis of the execution information.SELECTED DRAWING: Figure 4
