For any future readers, if you are trying to parse a string in the format yyyyMMddTHHmmssZ. Its easier to parse it with the following code. Code is in Kotlin. The iCalendar recur rule is an example of where this format might appear.

// Reads from end to start to accommodate case where year has 4+ digits. 10100 for example.
fun iso8601GetPart(hashMap : HashMap,noOfCharsFromEnd : Int?) : String{
    var str = hashMap.get("DATE_TIME")
    var endIndex = str.length
    if(str.get(str.length-1)=='T' || str.get(str.length-1)=='Z'){
        endIndex--
    }
    if(noOfCharsFromEnd==null){
        return str
    }else{
        hashMap.put("DATE_TIME", str.substring(0, endIndex - noOfCharsFromEnd))
        return str.substring(endIndex-noOfCharsFromEnd,endIndex)
    }
}

fun foo(){

    var hashMap = HashMap()
    hashMap.put("DATE_TIME",dateTimeString)

    var secOfMin = iso8601GetPart(hashMap,2).toInt()
    var minOfHour = iso8601GetPart(hashMap,2).toInt()
    var hourOfDay = iso8601GetPart(hashMap,2).toInt()
    var dayOfMonth = iso8601GetPart(hashMap,2).toInt()
    var monthOfYear = iso8601GetPart(hashMap,2).toInt()
    var years = iso8601GetPart(hashMap,null).toInt()
}
