How Can I Know Time In A Specific Country If I Am In A Differenet Country?

I am trying to do it this way 1. Get my time current time and time zone. 2. I know time zone of that specific country from Google. 3. Calculate difference in time zones. 4. Subtrac

Solution 1:

You can use Joda-Time library,

How can i know time in a specific country if i am in a differenet country?

http://www.joda.org/joda-time/apidocs/index.html

You can get the DateTimeZone depending on the Canonical ID defined in the Joda Time,

DateTimeZonezone= 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

//getcurrent moment indefaulttime zone
    DateTime dt =new DateTime();
    // translate toNew York localtime
    DateTime dtNewYork = dt.withZone(DateTimeZone.forID("America/New_York"));

here it is explained very perfectly which is my reference to your question

Solution 2:

x is the time zone id, there are a link of a list of them. Only need to feed the gettimeZone("with the time zone id") with the time zone of the city you want to know the time (I'm saying city because there are country with a lot of time zones like US or Russia).

TimeZone tz = TimeZone.getTimeZone("x")
