The invention provides a time synchronization method and device, and the method comprises the steps: receiving a first clock signal, sent by a clock source, at a current moment at a preset period, stopping transmitting time synchronization information to time receiving equipment under the condition that the communication with the clock source is monitored to be abnormal, and then transmitting the time synchronization information to the time receiving equipment after the communication with the clock source is monitored to be recovered. Determining a first time difference between the first clock signal received each time and a second clock signal in the time synchronization information sent to the time receiving device at the previous moment, and generating a third clock signal according to the sum of the second clock signal and a preset second time difference when the first time difference is greater than the preset second time difference, and sending time synchronization information containing the third clock
