Converting UTC dates to other timezones

SimpleDateFormat format = new SimpleDateFormat(\"yyyy-MM-dd HH:mm:ss\");
Date parsed = for         


        

Answer 1

Following code works fine for me to change a date from one tz to another. It considers the DayLightSaving also.

public static Calendar changeTimezoneOfDate(Date date, TimeZone fromTZ, TimeZone toTZ) {
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(date);
    long millis = calendar.getTimeInMillis();
    long fromOffset = fromTZ.getOffset(millis);
    long toOffset = toTZ.getOffset(millis);
    long convertedTime = millis - (fromOffset - toOffset);
    Calendar c = Calendar.getInstance();
    c.setTimeInMillis(convertedTime);
    return c;
}
