+The `lttng regenerate` command regenerates specific data of a tracing session.
+
+As of this version, the `metadata` and `statedump` actions are
+available.
+
+
+Regenerating a tracing session's metadata
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The `lttng regenerate metadata` action can be used to resample the offset
+between the system's monotonic clock and the wall-clock time.
+
+This action is meant to be used to resample the wall-clock time following a
+major link:https://en.wikipedia.org/wiki/Network_Time_Protocol[NTP] correction.
+As such, a system booting with an incorrect wall time can be traced before its
+wall time is NTP-corrected. Regenerating the tracing session's metadata ensures
+that trace viewers can accurately determine the events time relative to Unix
+Epoch.
+
+If you use man:lttng-rotate(1) or man:lttng-enable-rotation(1) to make
+tracing session rotations, this action regenerates the current and
+next trace chunks's metadata files.
