1pm in India doesn't give you any useful information about when the local culture sets work hour. I work with people in India, and often get IMs from them and when I look at their time I wonder why they are still working at 1am. Some off the teams over there need to work with Americans enough that they have adjusted their work hours to meet ours, while others have not. Thus I need to ask each team what a reasonable time for a meeting is no matter what.
