+Timezone Conversion (v0.12.0+)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Log messages that have a numeric timezone, like :code:`-03:00` or :code:`Z`
+for UTC, will be converted to the local timezone as given by the :envvar:`TZ`
+environment variable. For example, a timestamp ending in `-03:00` will be treated
+as three hours behind UTC and then adjusted to the local timezone.
+
+This behavior can be disabled by setting the
+:code:`/log/date-time/convert-zoned-to-local` configuration property to
+:code:`false`.
