For anyone with their feet in one time zone and their clock in another:
Pick any city in the world for your location, and any city for the time zone you'd like times shown in. See sunrise and sunset times, current and peak UV index, moon phase and illumination, temperatures, high tide and low tide, and astronomical sun/moon signs. Works in light mode or dark mode.
Sun, UV index, and temperatures come from Apple WeatherKit. Tides come from the nearest NOAA or IWLS station (US/Canada only). Moon phase and sign are computed locally from astronomical data.
