This query now works in datafusion 31:
```
DataFusion CLI v31.0.0
❯ select time '00:00:00' = time '00:00:00';
+-------------------------------------+
| Utf8("00:00:00") = Utf8("00:00:00") |
+-------------------------------------+
| true |
+-------------------------------------+
1 row in set. Query took 0.002 seconds.
```
