Discussion:

33.7.4 [thread.condition.condvar]: `condition_variable::wait_for` is required to compute the absolute time by adding the duration value to `chrono::monotonic_clock::now()`, but `monotonic_clock` is not required to exist.

[ Summit: ]

> Move to open. Associate with LWG 859 and any other monotonic-clock related issues.

[ 2009-08-01 Howard adds: ]

> I believe that 859 (currently Ready) addresses this issue, and that this issue should be marked NAD, solved by 859 (assuming it moves to WP).

[ 2009-10 Santa Cruz: ]

> Leave open, but expect to be fixed by N2969 revision that Detlef is writing.

[ 2009-11-18 Moved to Tentatively NAD after 5 positive votes on c++std-lib. Rationale added below. ]

Proposed resolution:

Rationale:

`condition_variable::wait_for` no longer refers to `monotonic_clock`, so this issue is moot.
