Regarding your time setting, I'm a little unsure what you want to do - there are only two things you can change - the timezone offset from GMT, which you set at the bottom of the screen by selecting the correct offset for your location from the list - I'm guessing Asia/Calcutta would be about right, and the way the date/time is displayed, which you choose from the list of five options at the top of the screen. What problems are you having ?
