About the time in Alton
Alton is on daylight saving time at the moment, which is why the offset reads UTC −4 instead of its winter value. Clocks go back on 1 November 2026, and anything scheduled across that date shifts by an hour.
Alton runs on America/Indiana/Marengo, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Sunrise today lands at 07:07 and sunset at 08:29 local time, giving 13h 22m of daylight. Those figures come from the city's own coordinates (38.12, -86.42) rather than a country-wide average, so they match what you would actually see from a window in Alton.
