Allowed conversions of java.time Objects

[Mark Rotteveel]

I am currently implementing some of the new java.time conversions for 
JDBC 4.2 and I am wondering if there might be some conversions missing 
from the changelog.

According to the changelog 
(https://jcp.org/aboutJava/communityprocess/maintenance/jsr221/JDBC4.2MR-Oct232013.pdf) 
the Table B-5 mapping for java.time.LocalDate is:
CHAR, VARCHAR, LONGVARCHAR and DATE

In this list I'd also expect TIMESTAMP (as a similar mapping does exist 
for java.sql.Date).

Similarly the mapping for LocalTime also misses TIMESTAMP (as does exist 
for java.sql.Time).

Is this intentional, or an omission? If the former: what is the rationale?

Similarly: shouldn't a conversion from OffsetTime and OffsetDateTime to 
TIME respectively TIMESTAMP be allowed as well?

PS Also note that the changelog talks about javax.time, while the JSR 
310 classes are in java.time
