About the time in Alton
Around 27,865 people live in Alton, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Sunrise today lands at 06:19 and sunset at 07:48 local time, giving 13h 28m of daylight. Those figures come from the city's own coordinates (38.90, -90.15) rather than a country-wide average, so they match what you would actually see from a window in Alton.
Alton runs on America/Chicago, which puts the city UTC −5 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.
