I didn't realize the JSON made a distinction. Should we just use getAsLong
everywhere that we're getting an integer value, or is there a difference in the
format of the value?

Timestamp is too long to fit into Java int.
OTOH, for all the other fields 32-bit integer is enough, so I'd not like to make
all the Java APIs to use "long".
