在Java中将UTC时间转换为本地时区

您的时区字符串格式错误。试试这个，

String sign = secondsFromGMT > 0 ? "+" : "-";secondsFromGMT = Math.abs(secondsFromGMT);      int hours = secondsFromGMT/3600;int mins = (secondsFromGMT%3600)/60;String zone = String.format("GMT%s%02d:%02d", sign, hours, mins);          TimeZone t = TimeZone.getTimeZone(zone);
