(-> prepped-data
    (tc/add-column :Year
                   (fn [ds]
                     (map #(.getYear %) (:Date ds))))
    (tct/index-by :Year)
    (tct/slice 1949 1950)
    )

This errors:

Time unit of from does not match index time unit: :int32

Something's wrong in the way slice is parsing the argument types here. Could be that there is a mismatch between an :int64 and :int32?
