+/**
+ * Cancel operations that take *too long*.
+ *
+ * You need to pass in an input `$promise` that represents a pending operation
+ * and timeout parameters. It returns a new promise with the following
+ * resolution behavior:
+ *
+ * - If the input `$promise` resolves before `$time` seconds, resolve the
+ *   resulting promise with its fulfillment value.
+ *
+ * - If the input `$promise` rejects before `$time` seconds, reject the
+ *   resulting promise with its rejection value.
+ *
+ * - If the input `$promise` does not settle before `$time` seconds, *cancel*
+ *   the operation and reject the resulting promise with a [`TimeoutException`](#timeoutexception).
+ *
+ * Internally, the given `$time` value will be used to start a timer that will
+ * *cancel* the pending operation once it triggers. This implies that if you
+ * pass a really small (or negative) value, it will still start a timer and will
+ * thus trigger at the earliest possible time in the future.
+ *
+ * If the input `$promise` is already settled, then the resulting promise will
+ * resolve or reject immediately without starting a timer at all.
+ *
+ * This function takes an optional `LoopInterface|null $loop` parameter that can be used to
+ * pass the event loop instance to use. You can use a `null` value here in order to
+ * use the [default loop](https://github.com/reactphp/event-loop#loop). This value
+ * SHOULD NOT be given unless you're sure you want to explicitly use a given event
+ * loop instance.
+ *
+ * A common use case for handling only resolved values looks like this:
+ *
+ * ```php
+ * $promise = accessSomeRemoteResource();
+ * React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) {
+ *     // the operation finished within 10.0 seconds
+ * });
+ * ```
+ *
+ * A more complete example could look like this:
+ *
+ * ```php
+ * $promise = accessSomeRemoteResource();
+ * React\Promise\Timer\timeout($promise, 10.0)->then(
+ *     function ($value) {
+ *         // the operation finished within 10.0 seconds
+ *     },
+ *     function ($error) {
+ *         if ($error instanceof React\Promise\Timer\TimeoutException) {
+ *             // the operation has failed due to a timeout
+ *         } else {
+ *             // the input operation has failed due to some other error
+ *         }
+ *     }
+ * );
+ * ```
+ *
+ * Or if you're using [react/promise v3](https://github.com/reactphp/promise):
+ *
+ * ```php
+ * React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) {
+ *     // the operation finished within 10.0 seconds
+ * })->catch(function (React\Promise\Timer\TimeoutException $error) {
+ *     // the operation has failed due to a timeout
+ * })->catch(function (Throwable $error) {
+ *     // the input operation has failed due to some other error
+ * });
+ * ```
+ *
+ * As discussed above, the [`timeout()`](#timeout) function will take care of
+ * the underlying operation if it takes *too long*. In this case, you can be
+ * sure the resulting promise will always be rejected with a
+ * [`TimeoutException`](#timeoutexception). On top of this, the function will
+ * try to *cancel* the underlying operation. Responsibility for this
+ * cancellation logic is left up to the underlying operation.
+ *
+ * - A common use case involves cleaning up any resources like open network
+ *   sockets or file handles or terminating external processes or timers.
+ *
+ * - If the given input `$promise` does not support cancellation, then this is a
+ *   NO-OP. This means that while the resulting promise will still be rejected,
+ *   the underlying input `$promise` may still be pending and can hence continue
+ *   consuming resources
+ *
+ * On top of this, the returned promise is implemented in such a way that it can
+ * be cancelled when it is still pending. Cancelling a pending promise will
+ * cancel the underlying operation. As discussed above, responsibility for this
+ * cancellation logic is left up to the underlying operation.
+ *
+ * ```php
+ * $promise = accessSomeRemoteResource();
+ * $timeout = React\Promise\Timer\timeout($promise, 10.0);
+ *
+ * $timeout->cancel();
+ * ```
+ *
+ * For more details on the promise cancellation, please refer to the
+ * [Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).
+ *
+ * If you want to wait for multiple promises to resolve, you can use the normal
+ * promise primitives like this:
+ *
+ * ```php
+ * $promises = array(
+ *     accessSomeRemoteResource(),
+ *     accessSomeRemoteResource(),
+ *     accessSomeRemoteResource()
+ * );
+ *
+ * $promise = React\Promise\all($promises);
+ *
+ * React\Promise\Timer\timeout($promise, 10)->then(function ($values) {
+ *     // *all* promises resolved
+ * });
+ * ```
+ *
+ * The applies to all promise collection primitives alike, i.e. `all()`,
+ * `race()`, `any()`, `some()` etc.
+ *
+ * For more details on the promise primitives, please refer to the
+ * [Promise documentation](https://github.com/reactphp/promise#functions).
+ *

+ * @param float $time
