Change the system time of the encoder.
1. Open the configuration page of the encoder that sends the video with incorrect time.
2. Click the CONFIG tab.
3. In the Configuration dialog box that is displayed, choose System Config > GENERAL.
System Time is different from the current time. It is inferred that the incorrect time on the Dahua encoder causes the time on the live video to be different from the host time.
Check the time configuration of the Dahua encoder
The time on the encoder is incorrect, which causes that the live video time to be different from the host time.
