You have to get time from server, They are lot of services but I prefer to use this one which gives you all data you need in UTC timezone: https://script.google.com/macros/s/AKfycbyd5AcbAnWi2Yn0xhFRbyzS4qMq1VucMVgVvhul5XqS9HkAyJY/exec (from http://davidayala.eu/current-time)
Then You have to Parse the service response and Get the Values you need.
Finally Instantiate Calendar and Set it with the value you got (day, week, month) and get the time in the timezone you want with the format you want ^^

P.S: You can also get the time in any timezone (It support many local time in India too) from the above API without any need for conversion.

Your welcome, well each step may need a little time and effort to implement. Let me know if this is working for you ^^ — Keivan Esbati, Mar 10 '17 at 08:02

get the time (time milliseconds) from internet server .(You can attach it response from the server ).
get the zone of the internet server let it be +2:45 ( also attach it in response from server ) and convert it to milliseconds.
get the timezone (+6:00) from your device and convert it to milliseconds.

4.now to the time milliseconds from the server add the following (time milliseconds from server +your timezone milliseconds - server timezone milliseconds

now convert result to your desired time date format

set your time zone to calendar and simply get DAY, Minute, Hour, DAY, WEEK etc.

TimeZone tz = TimeZone.getTimeZone("GMT+05:30");
Calendar c = Calendar.getInstance(tz);
String time = String.format("%02d" , c.get(Calendar.HOUR_OF_DAY))+":"+
              String.format("%02d" , c.get(Calendar.MINUTE))+":"+
              String.format("%02d" , c.get(Calendar.SECOND))+":"+
              String.format("%03d" , c.get(Calendar.MILLISECOND));
