Certain aspects of the present disclosure provide techniques for communicating time synchronized data between a client and a server. An example method generally includes synchronizing, by a client, a clock of the client with a clock source. The method also includes transmitting, from the client to a server, at an application level, information indicating the clock source, a cell identifier of a serving cell of the client, and accuracy of the clock source as a time value. The method further includes transmitting, from the client to the server, a message including data and a timestamp correlated to an event associated with the data based on the clock. The method also includes in response to the message, receiving, by the client from the server, generated data.
