1. A simulcast network comprising:

  • a plurality of transmitters, each transmitter including a clock having;

    (i) a sequentially advanceable counter for maintaining a local time value in response to a clocking signal;

    (ii) a signal generator for producing said clocking signal for application to said sequentially advanceable counter;

    (iii) a local time value processing circuit, connected to said sequentially advanceable counter, for producing a local time based on said local time value;

    wherein at least two of said signal generators corresponding to at least two of said clocks produce different clocking signals so that said sequentially advanceable counters associated therewith advance at different rates; and

    wherein said local time value processing circuits associated with said at least two of said signal generators are configured to produce local times that are substantially identical to each other.
