Hi. I am asking this because I want to understand the codebase better. I
build datafusion-cli with debug, run ` SELECT
to_timestamp_micros(9065525203050843594);` and get the error. However part of
the call stack is shown as follows:
```
19: 0x7ff66b198d9e -
chrono::naive::datetime::NaiveDateTime::from_timestamp
at
.cargo\registry\src\github.com-1ecc6299db9ec823\chrono-0.4.22\src\naive\datetime\mod.rs:131

at
\.cargo\registry\src\github.com-1ecc6299db9ec823\arrow-array-24.0.0\src\array\primitive_array.rs:496
```
So arrow is using `from_timestamp` function in
[temporal_conversions](https://github.com/apache/arrow-rs/blob/02cab5443c0703ce5fa86647b834f184bba172ba/arrow-array/src/temporal_conversions.rs#L123)
which means there is a need for a change in this part of the code.
I think it is not releated to this issue but datafusion uses
`from_timestamp` function in following
line:https://github.com/apache/arrow-datafusion/blob/f93642fd7782b0d530a5bff0fecec020b34e9bd1/datafusion/physical-expr/src/expressions/datetime.rs#L304
So we also need to fix it. If I am wrong, could you also suggest me tips
about how to debug/analyze these bugs?
