#3707 fix: Make date-time format of record `time_extracted` field consistent among all Singer message writer implementations Pull request opened by edgarrmondragon Summary by Sourcery Standardize the serialization format of the RecordMessage time_extracted field and align typing and tests with the new behavior. Bug Fixes: • Ensure RecordMessage time_extracted is serialized in a consistent UTC ISO 8601 format across Singer message writer implementations. Enhancements: • Tighten type hints for Message.from_dict using Self for more precise typing. Tests: • Add a serialization/deserialization roundtrip test for RecordMessage including time_extracted and update existing tests and snapshots to assert the new timestamp format and error message. meltano/sdk
