1. Time synchronizing device for synchronizing a router arranged between two communication networks, said synchronizing device comprising:

  • receiving means for receiving synchronizing data based on a reference time clock,and exploiting means for exploiting said synchronizing data (SYNC) so as to synchronize a local time clock used by said router with respect to said reference time clock,wherein said time synchronizing device comprises;

    intercepting means for intercepting at least one message (MSG) coming from at least one apparatus being a point of at least one of said networks, called the source network for said message (MSG), and directed to the other of said networks, called the target network for said message (MSG), said apparatus having a specific time clock,preparing means for preparing a time request intended for said apparatus, said time request being able to be executed in said apparatus so as to cause said synchronizing data based on said specific time clock to be obtained from said apparatus and to be transmitted back to said synchronizing device,sending means for sending said time request to said apparatus,and forwarding means for forwarding said intercepted message (MSG) to said target network after the preparing means have prepared said time request,said receiving means being intended to receive said synchronizing data from said apparatus and said exploiting means being able to exploit said synchronizing data so as to synchronize said local time clock with respect to said specific time clock, said receiving means, exploiting means, intercepting means, preparing means, sending means and forwarding means forming an operational set.
