Abstract: A time synchronization method and apparatus for network devices and a time synchronization server are disclosed, which relates to the field of communication technology, to solve the problem of failing to perform high-capacity and centralized time synchronization due to less timely processing of a time synchronization message in the related art. The method includes: a programmable logic device receiving and parsing a time synchronization message from a to-be-synchronized device in a physical layer, wherein the time synchronization message carries a synchronization parameter; the programmable logic device generating a reply message for the time synchronization message according to local reference time and update configurations of the synchronization parameter; and the programmable logic device sending the reply message and a link establishment and communication message from a CPU to the to-be-synchronized device in a preset order.
