Review comment:
What returns here is `java.sql.Time`, and its doc says
```
The date components should be set to the "zero epoch"
value of January 1, 1970 and should not be accessed.
```
Maybe some databases don't follow the requirement, but it doesn't matter, as
we call `rawTime.toLocalTime` which only access the hour:minute:second
components.
