1. A timing source for sending timing information via a packet network, said source comprising:

  • a first clock for generating said timing information;

    a packet forming section for forming a sequence of packets;

    an output section for transmitting said packets of said sequence via said network as packet bursts, each of which comprises a plurality of said packets with a time difference between consecutive packets of a same burst being less than a time difference between consecutive bursts, and said time difference between packets in the same burst being greater than a length of said packet, so that individual delays in transit times of at least some packets of the sequence are arranged to be minimized and to be consistent with each other across the network; and

    a time-stamping section for inserting into each said packet of said sequence a transmission time derived from said timing information generated by said first clock.
