You can probably use Joda Time - Java date and time API. You can get the DateTimeZone depending on the Canonical ID defined in the Joda Time,

DateTimeZone zone = DateTimeZone.forID("Asia/Kolkata");

Joda Time has a complete list of Canonical ID from where you can get TimeZone depending on the Canonical ID.

So, if you want to get the local time in New York at this very moment, you would do the following

    // get current moment in default time zone
    DateTime dt = new DateTime();
    // translate to New York local time
    DateTime dtNewYork = dt.withZone(DateTimeZone.forID("America/New_York"));
