Each integer in the List represents a number of nanoseconds since the Unix epoch in UTC that may correspond to the given calendar date and wall-clock time in the IANA time zone identified by timeZoneIdentifier.
     // When the input represents a local time repeating multiple times at a negative time zone transition (e.g. when the daylight saving time ends or the time zone offset is decreased due to a time zone rule change), the returned List will have more than one element. When the input represents a skipped local time at a positive time zone transition (e.g. when the daylight saving time starts or the time zone offset is increased due to a time zone rule change), the returned List will be empty. Otherwise, the returned List will have one element.
