Rock Island 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.
Rock Island sits at latitude 41.47, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 37m is one point on that curve, not a fixed value.
