 #### Overriding Log records
 
+???+ tip
+	Use `datefmt` for custom date formats - We honour standard [logging library string formats](https://docs.python.org/3/howto/logging.html#displaying-the-date-time-in-messages){target="_blank"}.
+
+	Prefer using [datetime string formats](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes){target="_blank"}? Set `use_datetime_directive` at Logger constructor or at [Lambda Powertools Formatter](#lambdapowertoolsformatter).
+
 You might want to continue to use the same date formatting style, or override `location` to display the `package.function_name:line_number` as you previously had.
 
 Logger allows you to either change the format or suppress the following keys altogether at the initialization: `location`, `timestamp`, `level`, `xray_trace_id`.
