What IST and CST mean here

IST here means India Standard Time, UTC+5:30, used across all of India with no daylight saving time. The half hour means India is never a whole number of hours away from the US or UK. IST is also used for Israel Standard Time (UTC+2) and Irish Standard Time (Ireland's summer time, UTC+1); to convert those, search for Tel Aviv or Dublin.

Here CST means US Central Time: Chicago, Dallas, Houston, Minneapolis, New Orleans and Winnipeg. That's CST (UTC−6) in winter and CDT (UTC−5) from March 8 to November 1, 2026. CST is also the abbreviation for China Standard Time (UTC+8) and Cuba Standard Time; for China, search for Beijing or "China Standard Time" in the converter.
