About these time zones
Central Standard Time (CST)
Central Standard Time (CST) is UTC-6. Most of the central United States and Manitoba use CST only in winter and switch to Central Daylight Time (CDT, UTC-5) from the second Sunday in March to the first Sunday in November. Most of Saskatchewan, most of Mexico and much of Central America stay on CST all year.
India Standard Time (IST)
India Standard Time (IST) is UTC+5:30 and is used across all of India as a single time zone. India does not observe daylight saving time, so IST never changes — but its difference from places that do (like US Eastern Time) changes twice a year.
