About the time in Union
If you are coordinating from another country, the shortcut is the working window: a normal Union day of 09:00–17:00 falls between 14:00–22:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
Sunrise today lands at 06:27 and sunset at 08:03 local time, giving 13h 36m of daylight. Those figures come from the city's own coordinates (42.24, -93.06) rather than a country-wide average, so they match what you would actually see from a window in Union.
The zone identifier America/Chicago is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Chicago keeps pointing at Chicago time whatever the date, which is why every timestamp on this page is built from it.
