1. An apparatus comprising:
interface circuitry to communicate via a network with a meter to obtain a watermark decoded from media presented by a media presentation device, the meter to monitor the media presented by the media presentation devices and to decode the watermark from the media;
watermark analyzer circuitry to determine the watermark decoded from the media included a decoded timestamp associated with a confidence that is lower than a first threshold;
comparator circuitry to determine that a second threshold number of values of the decoded timestamp match live media data corresponding to the watermark; and
timestamp adjustment circuitry to adjust the decoded timestamp based on the live media data to increase the confidence of the decoded timestamp.
