Scheduling between the two

There is no overlap between a nine-to-six working day in New Delhi and one in Buenos Aires — the gap is too wide. A call has to sit early or late for one side. Early morning in New Delhi is the usual compromise, since that is late afternoon or evening in Buenos Aires.

A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.

India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving
