datetime

To change the system time and date, enter the datetime {format}. The format must be 'yyyy-mm-dd hh24:mi:ss'. Note that if you manually change the system time and date while the NTP is enabled, you encounter the "Failed to set time: Automatic time synchronization is enabled" error. Therefore you need to disable the NTP before configuring the system time and date manually.
