 .. option:: --enable-time-check XXX
 
-   When this is enabled with a XXX value in microseconds, any thread that
-   runs for over this value will cause a warning to be issued to the log.
-   If you do not specify any value or don't include this option then
-   the default time is 5 seconds.  If --disable-time-check is specified
-   then no warning is issued for any thread run length.
+   This option is deprecated as it was replaced by the
+   :clicmd:`service cputime-stats` CLI command, which may be adjusted at
+   runtime rather than being a compile-time setting.  See there for further
+   detail.
 
 .. option:: --disable-cpu-time
 
-   Disable cpu process accounting, this command also disables the `show thread cpu`
-   command.  If this option is disabled, --enable-time-check is ignored.  This
-   disabling of cpu time effectively means that the getrusage call is skipped.
-   Since this is a process switch into the kernel, systems with high FRR
-   load might see improvement in behavior.  Be aware that `show thread cpu`
-   is considered a good data gathering tool from the perspective of developers.
