 For checking timing after a command has completed, check :ref:`$CMD_DURATION <variables-special>`.
 
+Your system most likely also has a `time` command. To use that use something like `command time`, as in `command time sleep 10`. Because it's not inside fish, it won't have access to fish functions and won't be able to time blocks and such.
