Module: DuckDBConverterTimestampMonkeyPatch

Defined in:
lib/active_record/connection_adapters/duckdb/timestamp_monkey_patch.rb

Overview

Monkey patch DuckDB::Converter to respect ActiveRecord.default_timezone. Based on: https://github.com/suketa/ruby-duckdb/blob/master/lib/duckdb/converter.rb Change: Use Time.utc instead of Time.local when ActiveRecord.default_timezone is :utc This fixes an issue where timestamps are interpreted in local timezone instead of UTC.

Run bin/verify_timestamp_patch to test compatibility with new versions.
