UTC时间转换

UTC时间转换

utc时间格式转换的时候，不同长度会异常

        String s0 = "2007-12-03T10:15:30" ;
        String s1 = "2007-12-03T10:15";

        String s2 = "2007-12-03 10:15:30";
        String s3 = "2007-12-03 10:15";

        LocalDateTime parse = LocalDateTimeUtil.parse(s0);
        String format = DateUtil.format(parse, "yyyy-MM-dd HH:mm:ss");
        System.out.println(format);

        LocalDateTime parse1 = LocalDateTimeUtil.parse(s1);
        String format1 = DateUtil.format(parse1, "yyyy-MM-dd HH:mm:ss");
        System.out.println(format1);

        LocalDateTime parse2 = DateUtil.parseLocalDateTime(s2);
        String format2 = DateUtil.format(parse2, "yyyy-MM-dd HH:mm:ss");
        System.out.println(format2);

        LocalDateTime parse3 = DateUtil.parseLocalDateTime(s3, "yyyy-MM-dd HH:mm");
        String format3 = DateUtil.format(parse3, "yyyy-MM-dd HH:mm:ss");
        System.out.println(format3);

结果

```java
2007-12-03 10:15:30
2007-12-03 10:15:00
2007-12-03 10:15:30
2007-12-03 10:15:00
