+## `process.threadCpuUsage([previousValue])`
+
+<!-- YAML
+added: v6.1.0
+-->
+
+* `previousValue` {Object} A previous return value from calling
+  `process.cpuUsage()`
+* Returns: {Object}
+  * `user` {integer}
+  * `system` {integer}
+
+The `process.threadCpuUsage()` method returns the user and system CPU time usage of
+the current worker thread, in an object with properties `user` and `system`, whose
+values are microsecond values (millionth of a second).
+
+The result of a previous call to `process.threadCpuUsage()` can be passed as the
+argument to the function, to get a diff reading.
