pearu opened a new issue, #54643:
URL: https://github.com/apache/arrow/issues/54643
### Describe the bug, including details regarding any error messages,
version, and platform.
Timestamp parsing with a `strptime` format rolls an impossible date over
into the next month. Where the platform's `strptime` accepts day `00` (macOS,
Windows), it is taken as the first of the month:
```python
import pyarrow as pa
import pyarrow.compute as pc
for value in ["2021-02-30", "2021-04-31", "2021-02-00"]:
try:
print(pc.strptime(pa.array([value]), format="%Y-%m-%d", unit="s")[0])
except pa.ArrowInvalid as e:
print(e)
```
Output on Linux (pyarrow 27.0.0.dev18):
```
2021-03-02 00:00:00
2021-05-01 00:00:00
Failed to parse string: '2021-02-00' as a scalar of type timestamp[s]
```
Output on macOS and Windows:
```
2021-03-02 00:00:00
2021-05-01 00:00:00
2021-02-01 00:00:00
```
Expected is a parse failure for all three values, as with the ISO-8601
parser: `pa.array(["2021-02-30"]).cast(pa.timestamp("s"))` raises
`ArrowInvalid: Failed to parse string: '2021-02-30' as a scalar of type
timestamp[s]`.
Found while working on #50146.
