A time synchronization method includes the following steps. First, network communication equipment receives time information sent by at least two time servers respectively, in which the time information includes time synchronization status information of each of the time servers. Then, it is determined whether time synchronization status of each of the time servers is normal or not according to the time synchronization status information. Finally, the network communication equipment selects to employ the time information provided by the time servers with the normal time synchronization status from the at least two time servers. Network communication equipment and a network communication system are also provided correspondingly. The network communication equipment is capable of employing the time information provided by the time server with the normal time synchronization status according to the time synchronization status of each of the time servers, thereby improving precision and reliability of the time information obtained by the network communication equipment.
