I am making a real-time tracking app. I have added a few users who are in 2 different time zones. I am trying to fetch the last time and date they were online, so far I have been able to fetch date and time, however, it is showing me time online in their country, I'd like to get the time converted based on my time zone.

    Please be a bit more specific when asking a question: *What have you tried so far with a code example?

You need to know in which GMT is their last updated time and then convert it into your GMT time. However it will be more simple if you make user to update their local time in your GMT.

public void timeZoneConverter() {

 //Date will return local time in 

 Date localTime = new Date(); 

 //creating DateFormat for converting time from local timezone to GMT

 DateFormat converter = new SimpleDateFormat("dd/MM/yyyy:HH:mm:ss");

 //getting GMT timezone, you can get any timezone e.g. UTC

 converter.setTimeZone(TimeZone.getTimeZone("GMT"));

 System.out.println("Local time : " + localTime);;
 System.out.println("Time in GMT : " + converter.format(localTime));
}
