Abstract:
     The invention discloses a method for testing accuracy of clock. Said method includes the folowing steps: a). before ageing, test link can write the debugging real-time clock into the real-time clock module; and b). after ageing, FT test link cn read out read out the debugging read-time clock so as to obtain the accuracy test result. Said invention reasonably utilizes the ageing proper time, the time of clock accuracy test is longer, so compared with existent technology the test error of said invetion can be relatively reduced. Besides, said invention also sdoptds the real-time clock of network time protocol synchronous debugging terminal, so that the accuracy for testing clock can be further raised.
