Julian Hyde commented on CALCITE-5266:
--------------------------------------
That "it rests on" phrase still sounds like AI. And I don't understand how what
you wrote pertains to fixing the case.
> Increase precision of TIMESTAMP, INTERVAL types to microseconds, nanoseconds

> Key: CALCITE-5266
> URL: https://issues.apache.org/jira/browse/CALCITE-5266
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Reporter: Dmitry Sysolyatin
> Priority: Major
>
> 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 ?
