Abstract

A time information obtaining device and a radio-controlled timepiece are shown. According to one implementation, the time information obtaining device includes the following. A code identifying section identifies each code of a code string in a radio wave. A first portion parity calculating section calculates a portion parity where a parity bit of a variable code is subtracted from a parity code showing a parity bit for a code string portion. A first portion parity deciding section decides a portion parity based on a calculated number of portion parities. A second portion parity deciding section obtains a portion parity from an invariable code other than the variable code. A parity confirming section confirms a match between the portion parities decided by the first portion parity deciding section and the second portion parity deciding section.
