Hello All,
I've started work on ARROW-582 to add Date/Time support for Java JSON files
and would just like to clear up a few things. I believe the Java Time type
is supposed to represent milliseconds since epoch, it is stored as a
FixedValueVector with a width of 4 bytes (equivalent to Java 'int'

Robert Nishihara commented on ARROW-607:
I believe this is already done in ARROW-55
I guess it would make sense to just store the time of day value in
milliseconds to go along with the DATE type that contains days since epoch,
which would fit into a 4 byte value. Only I see conflicting code in
TypeLayout.java that defines the schema as 64 bit width

Emilio,
Let me know if you need help.

Hi Bryan,
In the JSON representation we should use the integer representation of the
Timestamp. We should not depend on joda for this.
DATE is on 8 bytes => 64bits:
