Can someone point me to a list of the datatype keywords used in tech.ml.dataset?

I know what I functions I would use to parse the various columns with, but ->dataset wants me to write magic keywords keyed to columns names under :parser-fn…. trouble is, I have no idea what keywords to write. How do I know what magic keyword parses “HH:mm:ss” as a whatever the equivalent to a LocalTime is in tech.ml.dataset?

basically what are the magic keywords I put into my :parser-fn map that would allow to parse longs, LocalDates, and LocalTimes?

Do these appear correct?

(ds/->dataset {:parser-fn {:Birth      :local-date
                                   :Start-time :local-time
                                   :Date       :local-date
                                   :End-time   :local-time
                                   :Time       :int64
                                   :Age        :int64}})

I’ve also noticed something called :packed-local-time . Do I need to use that instead?
