Pull Request Overview

This PR adds support for YDB's extended date/time types: Date32, DateTime64, and Timestamp64, which allow representation of dates and timestamps beyond the range of standard Date, DateTime, and Timestamp types.

Key Changes:

• Added three new type classes (YqlDate32, YqlDateTime64, YqlTimestamp64) that extend the existing date/time types
• Registered these new types in the type system with appropriate visitor methods and YDB type mappings
• Added test coverage for the new types, including tests with dates before the Unix epoch (1969)
