About GMT to IST
The UK uses GMT (UTC+0) in winter and switches to British Summer Time, BST (UTC+1), in spring through autumn. India Standard Time (IST, UTC+5:30) doesn't observe daylight saving, so the gap to IST shifts between 5.5 and 4.5 hours depending on the time of year. This converter automatically uses the current correct offset.
