About UTC and CST
Chicago (America/Chicago) is UTC−6 as CST and UTC−5 as CDT. UTC (Etc/UTC) stays on the same numbers all year, so the gap shrinks from 6 hours to 5 hours when the US daylight saving period starts.
Central Time switches with Eastern and Pacific, on the second Sunday in March and the first Sunday in November. UTC does not switch.
