Yes, it is possible to handle UNIX timestamps in the no-code builder. You can refer to the [forum discussion](https://discuss.airbyte.io/t/3921) where a user shared a relevant configuration for handling UNIX timestamps with the DeclarativeStream. Here's the configuration snippet:

yaml incremental_sync:   type: DatetimeBasedCursor   cursor_field: "created"   datetime_format: "%s"   cursor_granularity: "PT1S"   start_datetime:     datetime: "{{ config['start_date'] }}"     datetime_format: "%Y-%m-%d %H:%M:%S"   end_datetime:     datetime: "{{ today_utc() }}"     datetime_format: "%Y-%m-%d"   step: "P1W"   start_time_option:     field_name: "created_after"     inject_into: "request_parameter"   end_time_option:     field_name: "created_before"     inject_into: "request_parameter"

You can use this configuration as a reference and modify the fields as required for your specific connector.
