A method for obtaining GNSS time in a GNSS receiver includes: obtaining a time relationship between a first clock signal and the received GNSS time; obtaining a clock value B1 of a second clock signal and further obtaining an associated clock value A1 of the first clock signal to obtain a first pulse relationship at a first time point; calculating a GNSS time C1 corresponding to the clock value A1 according to the time relationship; obtaining a clock value B2 of the second clock signal and further obtaining an associated clock value A2 of the first clock signal to obtain a second pulse relationship at a second time point; and calculating a GNSS time C2 according to the GNSS time C1, the clock value B1, and the clock value B2. Exemplary values of A1, B1, C1, A2 B2, and C2 can be TTick1, FN1, TOW1, TTick2, FN2, and TOW2, respectively.
