Run make with the variable DEVKITPPC set to the path of devkitPPC (as an environment variable or an argument passed thereto).
You can also set the variable DEFAULT_NTP_SERVER to override the default server of time.nist.gov (set in source/ntp.c).
In its simplest usage, launch the application without any arguments, at which point you can select the UTC offset of your time zone with the D-Pad of any connected Wii Remote or GameCube controller. After selecting your time zone, press A to continue.
Additionally, this application supports the following arguments:
-s, --server <server> the NTP server to use (default: time.nist.gov)
-t, --timezone <UTC offset> the UTC offset of your time zone
-a, --auto set the time without any user interaction,
with a 5 second period to be interrupted
(overrides previous instances of -w)
-w, --wait wait for the user to press A to set the time,
allowing for the UTC offset to be selected
(default, overrides previous instances of -a)
