Android手机中如果想以GMT形式（GMT+08:00）得到当前时区，可以参照如下代码所示：

public static String getCurrentTimeZone()    {        TimeZone tz = TimeZone.getDefault();        return createGmtOffsetString(true,true,tz.getRawOffset());    }    public static String createGmtOffsetString(boolean includeGmt,                                               boolean includeMinuteSeparator, int offsetMillis) {        int offsetMinutes = offsetMillis / 60000;        char sign = '+';        if (offsetMinutes < 0) {            sign = '-';            offsetMinutes = -offsetMinutes;        }        StringBuilder builder = new StringBuilder(9);        if (includeGmt) {            builder.append("GMT");        }        builder.append(sign);        appendNumber(builder, 2, offsetMinutes / 60);        if (includeMinuteSeparator) {            builder.append(':');        }        appendNumber(builder, 2, offsetMinutes % 60);        return builder.toString();    }    private static void appendNumber(StringBuilder builder, int count, int value) {        String string = Integer.toString(value);        for (int i = 0; i < count - string.length(); i++) {            builder.append('0');        }        builder.append(string);    }
