    Returns the current global process times.
    The return value is an object with five attributes:
 
-   * :attr:`user` - user time
-   * :attr:`system` - system time
-   * :attr:`children_user` - user time of all child processes
-   * :attr:`children_system` - system time of all child processes
-   * :attr:`elapsed` - elapsed real time since a fixed point in the past
+   * :attr:`!user` - user time
+   * :attr:`!system` - system time
+   * :attr:`!children_user` - user time of all child processes
+   * :attr:`!children_system` - system time of all child processes
+   * :attr:`!elapsed` - elapsed real time since a fixed point in the past
 
    For backwards compatibility, this object also behaves like a five-tuple
-   containing :attr:`user`, :attr:`system`, :attr:`children_user`,
-   :attr:`children_system`, and :attr:`elapsed` in that order.
+   containing :attr:`!user`, :attr:`!system`, :attr:`!children_user`,
+   :attr:`!children_system`, and :attr:`!elapsed` in that order.
