-ITU will parse the date-time correctly, however storing such values is not possible (in a `java.time.OffsetDateTime`), the `60` is therefore abandoned and the date-time will use `59` instead of `60`. 
+Since Java's `java.time` classes do not support storing leap seconds, ITU will throw a `LeapSecondException` if one is encountered to signal that this is a leap second. The exception can then be queried for the second-value.
