When iterating on the zip entries (and printing the time stamps)  of an old  sqljdbc.jar    the exception

"java.time.DateTimeException: Invalid value for SecondOfMinute (valid values 0 - 59): 60"
occured (issue has been seen on Windows).

Looks like the  dosToJavaTime function in  ZipUtils.java  of jdk9/jdk10 is a bit more "sensitive"
about the input it gets, compared to jdk8.
In both implementations :

java.base/share/classes/java/util/zip/ZipUtils.java
jdk.zipfs/share/classes/jdk/nio/zipfs/ZipUtils.java


the computation of the "seconds" values is done by

public static long dosToJavaTime(long dtime) {
...
(int) ((dtime << 1) & 0x3e));
...
}

0x3e is  binary 111110 or  decimal 62,  so larger values than the supported maximum 59 can occur
(maybe only with old/problematic archives but still we had such an example).

When looking a bit more closely into it, we found that the "second = 60" value  was coming from a  long value  930973758
that was passed to  ZipUtils.dosToJavaTime as  dtime argument.

(found this out by adding an enhanced chained exception to jdk9 showing the dtime value passed to dosToJavaTime).

Here is an example of the iteration on entries of such a "bad" zip file :

C:\JVM\openjdk10\bin\java  ZipIterate

A similar problem (dealing with days/months not seconds out of supported range) is described here :
https://bugs.openjdk.java.net/browse/JDK-8184940
"JDK 9 rejects zip files where the modified day or month is 0"


Compared to jdk8,  this is a regression so I think it would be good to have a better handling of problematic out of range seconds-values.

Do you think it would be sufficient to adjust the out of range seconds to the supported max-value 59 ?
Or is something more sophisticated prefered ?
I found the enhanced chained exception showing the  dtime long values helpful too, should I submit it ?
