Description

Currently values of typed literals TIMESTAMP and DATE are parsed to desired values by Timestamp.valueOf and Date.valueOf. This restricts date and timestamp pattern, and makes inconsistent to casting to TimestampType/DateType. Also using Timestamp.valueOf and Date.valueOf assumes hybrid calendar while parsing textual representation of timestamps/dates. This should be fixed by re-using cast functionality.
