Time should be be record type

Time is currently represented as Rosetta basic time time but in the Java representation it is a String which makes it hard to work with, e.g. hour, minute etc inaccessible in the model.

It should be a record type.

record type {
    hour int,
    minute int, 
    second int,
    milisecond int
}

Java implementation should include converting to and from ISO format

I think this would be a few days work to implement
