akravchukdremio opened a new issue, #48866:
URL: https://github.com/apache/arrow/issues/48866
### Describe the bug, including details regarding any error messages,
version, and platform.
The Gandiva precompiled time casting functions (`castTIMESTAMP_utf8` and
`castTIME_utf8`) incorrectly reject timestamp and time string literals with
more than 3 subsecond digits (beyond millisecond precision), instead of
truncating them as other implementations do.
Current behavior:
```cpp
castTIMESTAMP_utf8("2025-03-26 11:34:56.123456789")
// Returns: 0 (error)
// Error: "Invalid millis for timestamp value 2025-03-26 11:34:56.123456789"
castTIME_utf8("09:45:30.123456789")
// Returns: 0 (error)
// Error: "Invalid millis for time value 09:45:30.123456789"
```
Expected behavior:
```cpp
castTIMESTAMP_utf8("2025-03-26 11:34:56.123456789")
// Should return: equivalent to "2025-03-26 11:34:56.123" (truncated to
milliseconds)
castTIME_utf8("09:45:30.123456789")
// Should return: equivalent to "09:45:30.123" (truncated to milliseconds)
```
