-- For terms implying a distant past (e.g., "first", "oldest"), use the 'older_first' ordering.
+- For terms implying a distant past (e.g., "oldest"), use the 'older_first' ordering.
+- For terms implying ordering by time:
+  - start of the list (e.g., "first"), use the 'older_first' ordering.
+  - end of the list (e.g., "last", "latest"), opt for the 'newer_first' ordering.
 - If the user's query does not provide a clear time frame, or if the system's confidence in deducing a timeframe is below 70%, exclude 'start_time' and 'end_time' from the output.
 - If the deduced 'end_time' aligns with current time, omit the 'end_time'.
 - For unspecified time zones, timestamps should follow the 'YYYY-MM-DD hh:mm:ss' format.
