The invention provides a networking timing proofreading method and system, a computer, a storage medium and electrical equipment. The networking timing proofreading method comprises the steps that when power failure of a main power supply is detected, a standby power supply is started to store the first time currently recorded by a timer; when the main power supply is powered-on again, the currentsecond time of the timer is determined; the absolute value of the difference value between the second time and the first time is determined; whether the absolute value of the difference value is larger than the time length of power failure or not is judged, and a judgment result is generated; and if the absolute value of the difference value is larger than the time length of power failure, timingis started with the network time obtained through networking as the time reference after the main power supply is powered-on again. According to the technical scheme, when the electric quantity of the standby power supply is exhausted and the current time is not accurate, the network time obtained through networking serves as the time reference after the main power supply is powered-on again, thus the possibility of inaccurate timing of the timer when the electrical equipment is powered-off for a long time is reduced, and the reliability of operation of the electrical equipment is improved, so that the user experience is improved.
