About Central Standard Time (CST)
Central Standard Time (CST, IANA: America/Chicago, America/Mexico_City) is the time zone for the US Central region, central Mexico, and most of Central America, set at UTC-6:00. CST is the most populous US time zone by area covered and serves the Chicago-Dallas-Houston-Minneapolis corridor of ~80 million people across CST states (Texas, Illinois, Wisconsin, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Tennessee western, Kansas eastern, Nebraska eastern, Oklahoma, North Dakota, South Dakota, Kentucky western, Indiana western, Michigan UP, Florida panhandle) plus Mexico (Mexico City, Guadalajara, Monterrey since 2022 DST abolition), Honduras, Nicaragua, El Salvador, Costa Rica, Guatemala, Belize. CST observes DST (switching to CDT = UTC-5:00) per Energy Policy Act 2005 — except for Mexico nationally, which abolished DST in 2022 except for border zones aligning with US DST. CST affects: NYSE close at 15:00 CST, CME (Chicago Mercantile Exchange) commodity futures pit/electronic hours, Texas Medical Center coordinated patient handoffs.
About Newfoundland Standard Time (NST)
Newfoundland Standard Time (NST, IANA: America/St_Johns) is one of the world's few time zones with a 30-minute offset, set at UTC-3:30. NST is observed exclusively in the Canadian province of Newfoundland and Labrador (the island portion of the province and southeastern Labrador), serving approximately 500,000 residents. The 30-minute offset is preserved from the 1884 International Meridian Conference compromise that established time zones — Newfoundland Time was chosen because the island's longitudinal position (52.7°W central meridian for St. John's) falls between Atlantic and Eastern time zones, and the province's parliament voted to keep its own dedicated offset rather than align with neighboring provinces. NST observes Daylight Saving Time per the Canadian aligned schedule (switching to NDT = UTC-2:30 from March to November). Other 30/45-minute offset zones globally: India (IST UTC+5:30), Nepal (UTC+5:45), Myanmar (UTC+6:30), Iran (UTC+3:30), Afghanistan (UTC+4:30), Sri Lanka (UTC+5:30), Marquesas (UTC-9:30). NST affects: cod-fishing and offshore oil platform operations on the Grand Banks, ferry schedules to Cape Breton, and the historic Cabot Tower St. John's noon-gun.
