Alexander Korotkov 52ad1e6599 Refactor jsonpath's compareDatetime()
This commit refactors come ridiculous coding in compareDatetime().  Also, it
provides correct cross-datatype comparison even when one of values overflows
during cast.  That eliminates dilemma on whether we should suppress overflow
errors during cast.
