Jodatime Convert foreign to local timezone

Question

I've got a DateTime object in GMT, and I'd like to convert it to EST, which is my local timezone. How can I do this?

I'm confused because since EST is my local timezone, java is assuming that any DateTime objects are already in EST and so new DateTime(refDate, DateTimeZone.forID('EST')) isn't converting anything.

Since your Date is in GMT format, first you need to parse the Date using UTC, then convert it into your local time zone.

        String gmtTime = "2015-05-28 11:36:38.0";

        DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss.S");
        DateTime dateTime = fmt.withZoneUTC().parseDateTime(gmtTime);
        System.out.println("UTC Time: "+dateTime);

        DateTime now = dateTime.toDateTime(DateTimeZone.forID("EST"));
        System.out.println("Current EST Time " +now);

Output

UTC Time: 2015-05-28T11:36:38.000Z
Current EST Time 2015-05-28T06:36:38.000-05:00
