Well, joda-time is easier. Try something like this

DateTime dt = new DateTime(,,, ,, , );
DateTime dtIST = dt.withZone(DateTimeZone.forTimeZone(TimeZone.getTimeZone("IST");

Note here that the use of the three letter abbreviation is deprecated and that time zones should be referred to like "America/Los_Angeles" refers to PST.I haven't the time to get the corrsesponding for IST right now but something should be left as an exercise to the reader!

UPDATE: As Basil Bourque states in the comments, Joda-Time is in maintenance mode. Use java.time instead.
