There are three categories of date/time data types supported in both SQL and natively via API:
- Date
- Time
- Timestamp
Support for the timestamp type comes in two flavors, depending on whether the data being ingested into Kinetica is numeric (milliseconds since the Epoch) or string (date/time literal). Once ingested, both of these types and stored and processed in the same way.
