> Consider the following SQL expression:
> {code:sql}
> SELECT CAST('1' AS INTERVAL HOURS)
> {code}
> RexSimplify.simplifyCast reduces this to a RelLiteral with value 1 and type
> INTERVAL HOURS. However, the representation of short intervals should use the
> canonical value of the interval in milliseconds, so the correct value should
> be 3600000.
