About these time zones
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.
Gulf Standard Time (GST)
Gulf Standard Time (GST) is UTC+4 all year, used in the United Arab Emirates and Oman. Neither country observes daylight saving time. Saudi Arabia, Qatar, Bahrain and Kuwait are one hour behind on Arabia Standard Time (UTC+3).
