The TimedLockable requirements describe the characteristics of types that provide timed exclusive blocking semantics for execution agents (threads, processes, tasks).

### Requirements

For type `L` to be TimedLockable, the following conditions have to be satisfied for an object `m` of type `L`:

Expression | Requires | Return value
--- | --- | ---
m.try_lock_for(duration) | Blocks for the provided duration or until a lock on `m` is acquired. | true if the lock was acquired, false otherwise.
m.try_lock_until(time_limit) | Blocks until the provided time limit point is reached or a lock on `m` is acquired. | true if the lock was acquired, false otherwise.
