I'm trying to add a function to an application that allows the user to select a time zone for the app.
My application runs on Windows and uses time in all its functions (storing data, displaying it, deleting it etcetera): so time is very important here.
I just want the user to be able to select the time zone to use within the application itself - i.e. without having to close the application and change it in Windows settings.
How can I accomplish this?
