User Location options, located in the Calendar Preferences tab, let you specify your geographical location. Q++ will use this information to display moon phases and sunrise/sunset information in the Date-Time Tool Tab, located at the top right of the Q++ Main Window.
You can either enter the information (latitude, longitude, ...) directly, or you can click on the lookup button of the Name control to select a city from a list of over 2000 cities worldwide. Once that selection is made, the appropriate information will automatically be filled-in. Note that the included database of timezones is old (circa. 2003) and is not being maintained. Therefore you should refer to an up-to-date source of timezone information such as www.timeanddate.com.
•Once that information is filled in you can modify it as you wish (if, for example the rule for summer times has changed). However these changes do not affect the database containing the list of cities.
•In particular, the name of your location can and should be changed as it will be displayed in the Main Window, as it is entered here in the Preference dialog. Although most city names do not change from one language to the other, note that for the moment, the list of cities is in French.
Finally, use the Dawn and Dusk option to specify how the dawn and dusk times displayed in the date tab of the Q++ Main Window are calculated.
