IST currently runs on UTC+5:30 and GMT on UTC+1, so iST is 4 hours 30 minutes ahead of GMT. IST does not observe daylight saving time, and gMT is currently on daylight saving (summer) time. Because both cities follow their own clock rules, the 4 hours 30 minutes gap you see today can shift by an hour around the spring and autumn changeovers, which is why this page calculates every value live from the official time zone database instead of a fixed offset. For meetings, the best shared working window today is 14:00–18:00 IST time, when both offices are inside normal 09:00–18:00 hours.
