determine, based on the length of time, whether at least part of derived temporal information associated with the point of interest in the local database of points of interest is likely correct, the determining including comparing the length of time to a predetermined time threshold, the predetermined time threshold corresponding to a length of time sufficient to infer that a user had a reason to remain at the point of interest; and
upon determining that the at least part of the derived temporal information is not likely correct, update information associated with the point of interest in the local database of points of interest to identify the at least part of the derived temporal information associated with the point of interest as being not likely correct.
