Abstract: A method and system at the site of a user are disclosed that provide for a shared understanding between a first and second content providing module on an applicable timing model by an explicit exchange of information on the content providing steps and of associated time values for one or more of these steps, adding unambiguous meaning to each of the content providing steps prior to presenting the first and second content to the user. The time delay information for specific content providing steps as received from the first content providing module can be used by other modules to determine when to provide content to the user. The timing model for the first content providing module is enriched with information enabling that timing information of the first content providing module can now be applied unambiguously by the second content providing module having a different timing mode.
