Thanks for the PR @snuyanzin. However, I think we should not change the
exception string but should improve the
`org.apache.flink.api.common.typeinfo.SqlTimeTypeInfo#toString` method instead.
Similar to `org.apache.flink.api.java.typeutils.GenericTypeInfo#toString`. The
type class is too little information. The type information is necessary in most
cases.---
