An Indian evening, a New York morning
Eastern Time is ten and a half hours behind India in winter and nine and a half during daylight saving. A New York working day from 09:00 to 18:00 runs from 18:30 to 03:30 in India in summer, and from 19:30 to 04:30 in winter.
So the messages a New York customer waits for should be sent by systems, not people. Your order or ticketing system calls InfiQ's API when something changes, and the update goes out in the New York afternoon while your office in India is dark.
Replies are the harder part. A question sent at lunchtime in Manhattan arrives late at night in India, and the 24-hour window lets your team answer it the next Indian morning without a template. Anything later than that needs an approved utility template, so decide early whether you need an evening shift.
