Abstract: In general, various aspects of the techniques described in this disclosure provide time synchronization for encrypted traffic in a computer network. In one example, the disclosure describes an apparatus, such as a network device, having a control unit for a network device in a computerized network having a topology of network devices; and a forwarding unit operative to determine a release time for sending a synchronization packet in accordance with a time synchronization protocol; modify the synchronization packet to include a release timestamp specifying the release time; sending a time value via sideband data associated with the synchronization packet, wherein the time value is based on the release time specified by the release timestamp; and schedule transmission of the synchronization packet for a time corresponding to the time value in the sideband data, the synchronization packet to be transmitted to a destination network device.
