An implementation method for a time stamp of a distributed storage system, characterized in that the method comprises: each server node of the distributed storage system maintaining a local time stamp; each server node periodically sending a data package carrying a current time stamp maintained locally to the other server nodes in the distributed storage system; and each server node updating the local time stamp according to the received data package; wherein each server node updating the local time stamp according to the received data package comprises: parsing the received data package to obtain a time stamp and a check bit; judging whether the check bit is correct, and if the check bit is incorrect, not updating the local time stamp and discarding the time stamp obtained by parsing; when the check bit is correct, storing the time stamp obtained by parsing; judging whether the difference between the value of the time stamp obtained by parsing and the value of a time stamp stored previously is within the range of a preset check threshold, and when the difference is not within the range of the check threshold, not updating the local time stamp; and when the difference is within the range of the check threshold, judging whether the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, and if the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, updating the local time stamp using the time stamp obtained by parsing; and when the value of the time stamp obtained by parsing is not greater than the value of the local current time stamp, not updating the local time stamp. each server node of the distributed storage system maintaining a local time stamp; each server node periodically sending a data package carrying a current time stamp maintained locally to the other server nodes in the distributed storage system; and each server node updating the local time stamp according to the received data package; wherein each server node updating the local time stamp according to the received data package comprises: parsing the received data package to obtain a time stamp and a check bit; judging whether the check bit is correct, and if the check bit is incorrect, not updating the local time stamp and discarding the time stamp obtained by parsing; when the check bit is correct, storing the time stamp obtained by parsing; judging whether the difference between the value of the time stamp obtained by parsing and the value of a time stamp stored previously is within the range of a preset check threshold, and when the difference is not within the range of the check threshold, not updating the local time stamp; and when the difference is within the range of the check threshold, judging whether the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, and if the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, updating the local time stamp using the time stamp obtained by parsing; and when the value of the time stamp obtained by parsing is not greater than the value of the local current time stamp, not updating the local time stamp. parsing the received data package to obtain a time stamp and a check bit; judging whether the check bit is correct, and if the check bit is incorrect, not updating the local time stamp and discarding the time stamp obtained by parsing; when the check bit is correct, storing the time stamp obtained by parsing; judging whether the difference between the value of the time stamp obtained by parsing and the value of a time stamp stored previously is within the range of a preset check threshold, and when the difference is not within the range of the check threshold, not updating the local time stamp; and when the difference is within the range of the check threshold, judging whether the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, and if the value of the time stamp obtained by parsing is greater than the value of the local current time stamp, updating the local time stamp using the time stamp obtained by parsing; and when the value of the time stamp obtained by parsing is not greater than the value of the local current time stamp, not updating the local time stamp.
