private static String calcTimezone(Calendar cal) {
    Date date = cal.getTime();//from   w w w . j a  v  a  2  s  .co  m
    TimeZone z = cal.getTimeZone();
    int tz = z.getRawOffset();

        tz = -tz;
    }

    int tzH = tz / (60 * 60 * 1000); // Integer divide towards zero.
    int tzM = (tz - tzH * 60 * 60 * 1000) / (60 * 1000);
