Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for correcting client-assigned timestamps. In one aspect, a method includes receiving, by one or more servers, a data packet that includes (i) data referencing one or more client-side events, (ii) data referencing a respective time that a client has assigned to each event, and (iii) data referencing a transmission time that the client has assigned to the data packet. The method also includes assigning, by the one or more servers, a receipt time to the data packet, and comparing, by the one or more servers, the transmission time that the client has assigned to the data packet to the receipt time that the one or more servers have assigned to the data packet, to determine a time correction factor.
