CST vs UTC — What You Need to Know

CST (Central Standard Time) is UTC-6, covering the central United States including Illinois, Texas, and Minnesota. From March to November, Central Time uses CDT (UTC-5) during Daylight Saving Time.

UTC (Coordinated Universal Time) is the global time standard, used in servers, APIs, aviation, and international scheduling. UTC never changes for DST.

Chicago's 9 AM stand-up is 15:00 UTC in winter — useful for server logs and cross-timezone scheduling. In summer (CDT), that same 9 AM meeting is 14:00 UTC.
