About the time in South Lyon
The zone identifier America/Detroit is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Detroit keeps pointing at Detroit time whatever the date, which is why every timestamp on this page is built from it.
South Lyon runs on America/Detroit, 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.
Around 11,327 people live in South Lyon, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
