A vital signs information measuring apparatus includes: an internal clock； a first correcting section which is configured to execute first time correction on the internal clock by using time information, and which is configured to store a time correction amount in a storage section, the time correction amount indicating a degree of deviation of a time of the internal clock at a timing when the first time correction is performed by the first correcting section； and a second correcting section which, in a case where it is detected that the first correcting section fails to normally correct the time of the internal clock at a prescribed timing, is configured to perform second time correction on the internal clock by using a history of the time correction amount stored in the storage section.
