About these two clocks

CST — Central Time. Used in Chicago, Dallas, Houston, Mexico City is separate. CST is the winter name; in summer the same clocks run on CDT (UTC−5). Conversions here follow the clocks.

UTC — Coordinated Universal Time. Used in the world reference clock used by servers, aviation and logs. UTC never changes for daylight saving time.

All figures on this page come from the IANA time zone database (the same data your phone and laptop use), evaluated for the date in question. Abbreviations are ambiguous — “IST” also means Irish or Israel Standard Time, and “CST” is China Standard Time in Asia — so this page uses America/Chicago and UTC explicitly.
