Abstract
Disclosed is a time information obtaining device comprising: a reception section to receive a standard time radio wave; an input waveform data generation section to generate input waveform data, based on data having the unit of time length; an estimated waveform data generation section to generate estimated waveform data, wherein the estimated waveform data comprises the value in which each sample point is described by the plurality of bits, and has the same time length as the input waveform data, and comprises at least one code which configures the time code, and a waveform of the estimated waveform data is sequentially shifted by a predetermined sample; a correlation value calculation section to calculate a correlation value; a correlation value comparison section to compare the correlation value to calculate an optimal value; and a control section to specify a beginning position of a second in the time code.
