I have registered in a conference which is supposed to be in India. The presentation time of the papers are defined and my presentation is at 4 PM. I'm not from India and I need to convert the time to the time of my own country, but I don't know the timezone of the defined time. I mean I don't know if 4 PM is defined based on India time or Greenwich time.
I want to send an email and ask them, but I don't know how I can ask this. What is the best way of asking the timezone?
