**Modified  datatime object 👍 ** 
i have changed view values to numeric of date and missing data found in pd series is returns Nan when coerce errors . 

**Example for solved changes 💯 **
```
>>> pd.to_numeric(pd.Series(datetime(2021, 8, 22)), errors="coerce")
[OUT]
0    20210822
dtype: int64

>>> pd.to_numeric(pd.Series(pd.NaT), errors="coerce")
[OUT]
0   NaN
dtype: float64

>>> s = pd.to_numeric(datetime(2021, 8, 22), errors="coerce")
0 20210822
dtype: Int64
>>> s = pd.to_numeric(pd.NaT, errors="coerce")
