Signal K Node server plugin to set system time on time data from GPS
When this option is checked, set-system-time plugin will try to use sudo to set the date.
It's required that sudo have a password-less access to the date command.
To give sudo a no password access only to the date command, you can add the following line to your sudoers file :
pi ALL=(ALL) NOPASSWD: /bin/date
--- In this example, pi is the username that run the signalk server. Yours could be different.
