This is a small utility developed for the Nintendo Wii which will synchronize the system time to the NTP time.

User guide

There are two options on how to use this utility:

Option 1:

• Manual adjustment using the Wiimote or GameCube controller.
• Timezones are not remembered and will have to be adjusted manually by the user.

Option 2:

• Configuration using a timezone configuration file. Create a tzdb.cfg on the root of the SD card in your Wii.
• Populate it with the following lines: http://api.timezonedb.com/v2.1/get-time-zone?key=MY_API_KEY&format=json&by=zone&zone=America/Toronto&fields=gmtOffset
• Autosave.
• Register an account at timezonedb.com.
• Change the MY_API_KEY to the api key you will receive.
• Change the timezone from the list available at timezonedb.com.
• If you want the utility to exit automatically after adjustment keep the autosave, otherwise remove.

Implementation details:

• Timekeeping is done by reading the (ever incrementing) Real Time Clock (RTC) and a counter bias stored in a system configuration.
• If you adjust your time in the wii menu or by using this program the counter bias is changed.
• There is always a risk that updating this counter bias could corrupt your system as it is part of the system configuration.
• The author shall not be held responsible if this would happen. This has been tested by the author on the Wii system.

Changelog

v1.2.0

• It includes timezone with DST detection and an automatic mode requiring no user input.
