1. A method comprising:
receiving by a client an ongoing media stream that includes a watermark steganographically encoding a timestamp of a portion of the media stream;
extracting by the client the timestamp from the watermark;
computing by the client a time offset based on a comparison of the extracted timestamp with client-time according to a clock of the client; and
using by the client the computed time offset as a basis to control when the client will carry out a content-related action in the media stream.
