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
