> Current implementation of casting UTF8String to DateType/TimestampType uses hybrid calendar
(Gregorian + Julian). The ticket aims to unify conversion of textual date/timestamp representation
to DateType/TimestampType and use Proleptic Gregorian calendar. More precisely, need to port
stringToTimestamp and stringToDate on java.time of Java 8 API.
