What does this tool do?

It reports illumination and age, lists the next eight lunation quarters, and lists solar/lunar eclipses for three years.

Are eclipse times local?

Peaks are UTC instants from a geocentric/global search, not a city-specific visibility map.

No. Searches run in the browser.

The named phase uses 45° bins; the exact new moon is the quarter event in the list.

UTC datetime

Phase angle and illumination come from astronomy-engine. Quarter and eclipse searches walk forward from the chosen UTC epoch.
