 |units| Selecting units allows switching units from km/h (kilometer per hour) and °C (degree Celcius) to mph (miles per hour) and °F (degree Fahrenheit). Possible options are `"metric"`, `"imperial"` or `"aviation"` (Celsius, Degree/Knots). |
 |hours | Which time format do you prefer? This will change the sunrise and sunset times from 24-hours format to 12-hours format. Possible options are `"24"` for 24-hours and `"12"` for 12-hours.|
 |update_interval | The update delay between two updates in minutes. By default there is always an update on a full hour.|
