The present disclosure is related to a method, a system, a non-transitory computer-readable medium and a computer program product for calibrating time of a physiological data. The method includes providing a physiological monitoring device for storing a physiological data with a first measurement time, and the physiological monitoring device has a first counting time. A wireless communication channel is established between the physiological monitoring device and a time calibration device having a second counting time. The first counting time and the second counting time are compared to obtain a counting time deviation value, and the counting time deviation value is compared with a predetermined time deviation value. If the counting time deviation value exceeds the predetermined time deviation value, the first measurement time and the counting time deviation value are computed to obtain a calibrated measurement time of the physiological data.
