Use `timeout()` or `timeout_at()` rather than instantiating this class directly.
whenreturnNc X t j | _ d| _ d| _ || _ y)zSchedule a timeout that will trigger at a given loop time.
- If `when` is `None`, the timeout will never trigger.
- If `when < loop.time()`, the timeout will trigger on the next
iteration of the event loop.

Useful in cases when you want to apply timeout logic around block
of code or in cases when asyncio.wait_for is not suitable. For example:
>>> async with asyncio.timeout(10): # 10 seconds timeout
... await long_running_task()
delay - value in seconds or None to disable timeout logic
long_running_task() is interrupted by raising asyncio.CancelledError,
the top-most affected timeout() context manager converts CancelledError
into TimeoutError.

Like timeout() but argument gives absolute time in the same clock system
as loop.time().
Please note: it is not POSIX time but a time with
undefined starting base, e.g. the time of the system power on.
>>> async with asyncio.timeout_at(loop.time() + 10):
... await long_running_task()
when - a deadline when timeout occurs or None to disable timeout logic
long_running_task() is interrupted by raising asyncio.CancelledError,
the top-most affected timeout() context manager converts CancelledError
into TimeoutError.
