     #### Usage
     
-        M20 [ L ]
+        M20 [ L | T ]
     #### Parameters
-    - `L` - Reports ling filenames instead of just short filenames. Requires host software parsing.
+    - `T` - Report timestamps as well. The value is one uint32_t encoded as hex. Requires host software parsing (Cap:EXTENDED_M20).
+    - `L` - Reports long filenames instead of just short filenames. Requires host software parsing (Cap:EXTENDED_M20).
