Abstract:
1. A time adjustment device comprising: a time information generating unit that generates time information including internal time data and outputs the generated time information; a reception unit that receives satellite signals transmitted sequentially from a positioning information satellite in subframe information units, each containing time-related information of the positioning information satellite (“satellite time-related information”), and at least one subframe information unit containing information pertaining to an operating status of the positioning information satellite (“satellite health information”); an external input unit that generates command information, through manual operation of an external operating unit, instructing the reception unit to enter reception mode; a reception timing configuration unit that sets the start time of reception by the reception unit when in the reception mode, so that the subframe information unit containing the satellite health information can be acquired at a time determined by the internal time data; and a time adjustment information storage unit that stores the satellite time-related information as time adjustment information; wherein the generated time information is adjusted based on the time adjustment information.
