Time Settings incorrect
If the Wii console isn't keeping track of the time when it is unplugged from the wall, then the system's internal battery needs to be replaced. This replacement can only be performed by Nintendo technicians. Please click here to get in contact with our Consumer Support department
If the Wii console does not keep proper time while plugged in, then there appears to be a problem with the Wii console itself and the system will need to be repaired. Please contact Nintendo Consumer Service for more information.
Please Note: The Wii uses a 24-hour clock rather than a 12-hour clock (for example: 4:00 p.m. appears as 16:00). The clock does not automatically adjust for Daylight Savings Time.
