Required methods

Parsing string values and return a TimeChunked

Parsing string values and return a DateChunked Different from as_date this function allows matches that not contain the whole string e.g. “foo-2021-01-01-bar” could match “2021-01-01”

Parsing string values and return a DatetimeChunked Different from as_datetime this function allows matches that not contain the whole string e.g. “foo-2021-01-01-bar” could match “2021-01-01”

Parsing string values and return a DateChunked

Parsing string values and return a DatetimeChunked
