Automatic schedule is too short (late) [wishlist]

The automatic schedule of Nightlight is not working well for me - the icon and redshifting starts at 19:00, which in November at my location in Central Europe is waaaay beyond the dawn. My other laptop with Gnome kicked nightlight into work before 16:00! Afaik Gnome is using geolocation service to determine when to switch on nightlight, and so did Redshift app back in Loki (although I could set the location there if I didn't want to give off my location).

Nightlight in Juno doesn't seem to use geolocation (it's not listed in Privacy tab), but frankly, it doesn't seem to use any other clue, not even the date in the calendar (let alone timezone or locale settings, which could be tricky I admitt).

Is there a way to opt in to geolocation-based scheduling? At least a choice of automatic geolocation or putting a pin into a map would be great.
