Dmitry Sysolyatin updated CALCITE-5266:
---------------------------------------
Description:
TIMESTAMP, INTERVAL types can preserve only milliseconds, because internal
TIMESTAMP representation is Long. But it would be good to extend precision to
microseconds and nanoseconds.
I suggest to use standard java.time classes for representing TIMESTAMP and
INTERVAL type internally:
# TIMESTAMP type can be represent like java.time.Instant
# INTERVAL type can be represent like java.time.Period + java.time.Duration
What do you guys think ?
