Daylight Saving Time: UTC and IST
UTC is the universal time standard and the basis for all other offsets. It never observes DST, making it the most stable reference for logging, APIs, and international scheduling.
India does not observe Daylight Saving Time. IST (UTC+5:30) is fixed year-round. India's unusual 30-minute offset was standardized in 1906 and applies to the entire country despite spanning nearly 30 degrees of longitude.
