The times on the HomeWizard are controlled locally on the gateway itself. You can configure the correct time using the 'HomeWizard configuration tool'. Make sure you use the correct time zone during this installation.

The HomeWizard only knows the times of sunrise and sunset when you have been assigned the  location. You can install this by using 'Geofence' and or Sharedweather.

Then check the relevant 'Tasks based on time trigger' is correct.
