+correction. As such, LTTng can trace a system booting with an incorrect
+wall time before its wall time is NTP-corrected. Regenerating the
+metadata of the selected tracing session ensures that trace readers can
+accurately determine the event record timestamps relative to the
+Unix epoch.
+
+Note that if you plan to rotate (see man:lttng-concepts(7) to learn
+more) the selected tracing session, this target only regenerates the
+metadata stream files of the current and next trace chunks.
+
+[IMPORTANT]
+====
+You can only use the `metadata` target when the selected
+tracing session:
