 A steady clock is not necessarily a monotonic clock. N3128 (http://www

 .open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3128.html) is the proposal
 that removed monotonic clocks and added steady clocks and includes the
 rationale:


 {{{
     The implementation of the timeout definition necessarily depends on a
 steady clock, one that cannot be adjusted. A monotonic clock is not
 sufficient. While one could be implicit in the standard, below we make one
 explicit.

     Given a steady clock, the monotonic clock seems to be of marginal
 utility, and we replace the monotonic clock with the steady clock.

 }}}

 Please, let me know if there is something in the documentation that say
 something that doesn't conforms to the C++11 standard.
