andygrove opened a new issue, #468:
URL: https://github.com/apache/datafusion-comet/issues/468
### Describe the bug
In `CometExpressionSuite` we have two tests that are ignored for Spark 3.2
and 3.3.
```scala
test("cast timestamp and timestamp_ntz to string") {
// TODO: make the test pass for Spark 3.2 & 3.3
assume(isSpark34Plus)
```
```scala
test("cast timestamp and timestamp_ntz to long, date") {
// TODO: make the test pass for Spark 3.2 & 3.3
assume(isSpark34Plus)
```
Enabling these tests for 3.2 shows incorrect output:
```

```
We should fall back to Spark rather than produce the wrong results.
