Questions
What time is 3 PM CST in IST?
3:00 PM Central Time is 1:30 AM the next day India Standard Time in northern summer and 2:30 AM the next day in winter, because only one side changes its clocks, or they change on different dates.
Is CST the same as Central Time?
Not always. Central Time is CST (UTC−6) in winter and CDT (UTC−5) in summer. This is US Central Time, not China Standard Time. This page uses Central Time as Chicago lives it, and says which one applies on the date you pick; choose "CST, fixed UTC−6" to use the fixed offset instead.
Does IST change for daylight saving?
IST here is India Standard Time (UTC+5:30), which has no daylight saving. Not Irish or Israel Standard Time.
