## Details

A `parttime`

object (short for its class name, `partial_time`

), is a vector
representation of a numeric matrix containing rows for each vector element
and a column for each datetime field.

To inspect the internal representation of a `partial_time`

class vector, you
can use `vctrs::field(<pttm>, "pttm_mat")`

.
