-- Filter `timestamp_local(default)` converts a UNIX timestamp to its naive string representation as date/time in your local timezone. If that fails, returns the `default` value, or if omitted the unprocessed input value. If timezone information is needed in the string, use `timestamp_custom` instead.
-- Filter `timestamp_utc(default)` converts a UNIX timestamp to its naive string representation representation as date/time in UTC timezone. If that fails, returns the `default` value, or if omitted the unprocessed input value. If timezone information is needed in the string, use `timestamp_custom` instead.
+- Filter `timestamp_local(default)` converts a UNIX timestamp to the ISO format string representation as date/time in your local timezone. If that fails, returns the `default` value, or if omitted the unprocessed input value. If a custom string format is needed in the string, use `timestamp_custom` instead.

 - Filter `timestamp_custom(format_string, local_time=True, default)` converts an UNIX timestamp to its string representation based on a custom format, the use of a local timezone is default. If that fails, returns the `default` value, or if omitted the unprocessed input value. Supports the standard [Python time formatting options](https://docs.python.org/3/library/time.html#time.strftime).
