What is central prevailing time?

Answer 1

Central Prevailing Time is the time zone currently (at any given time) in effect between the North American time zones of Central Standard Time (CST or UTC-6) and Central Daylight Saving Time (CDT or UTC-5).

The time in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and most of the Province of Saskatchewan, Canada is always Central Standard Time. However, the Central Prevailing Time in large parts of Canada and the United States and in six Mexican cities along the U.S. border is Central Standard Time from 2 AM CDT (07:00 UTC) on the first Sunday of November until 2 AM CST (08:00 UTC) on the second Sunday of March and Central Daylight Saving Time during the rest of the year, and in most of Mexico, the Central Prevailing Time is Central Standard Time from 2 AM CDT on the last Sunday of October until 2 AM CST on the first Sunday of April and Central Daylight Saving Time during the rest of the year.
