描述

Is there an existing issue for this?

  • I have searched the existing issues

Is your feature request related to a problem? Please describe.

Timestamp is a very common datatype in all databases. We can convert timestamp into int64, but this will be a overhead for the user.

We can follow the definition of PG https://www.postgresql.org/docs/current/datatype-datetime.html about what datetime data type should behave

We need to mainly support 4 data types. Date w/without timezone time w/without timezone

And main display method and filter function on top of it

研究方向
Examine Milvus's current type system in the `types` package and how timestamps are handled. Review PostgreSQL's datetime documentation for date/time data types and their behaviors. Look at existing issues or discussions in the repo related to datetime support. Focus on implementing four types: date, time, timestamp with time zone, timestamp without time zone, and their comparison and display functions.
