class_docstr: Series.dt namespace.
class_docstr_tok: ["Series.dt","namespace","."]
docstr: Create a naive Datetime from an existing Date/Datetime expression and a Time.
  
  If the underlying expression is a Datetime then its time component is replaced,
  and if it is a Date then a new Datetime is created by combining the two values.
  
  Parameters
  ----------
  time
      A python time literal or Series of the same length as this Series.
  time_unit : {'ns', 'us', 'ms'}
      Unit of time.
  
  Examples
  --------
  >>> from datetime import datetime, time
  >>> s = pl.Series(
  ...     "dtm",
  ...     [datetime(2022, 12, 31, 10, 30, 45), datetime(2023, 7, 5, 23, 59, 59)],
  ... )
  >>> s.dt.combine(time(1, 2, 3, 456000))
  shape: (2,)
  Series: 'dtm' [datetime[μs]]
