# init(upstream:interval:tolerance:scheduler:options:)

Creates a publisher that delays delivery of elements and completion to the downstream receiver.

```
init(upstream: Upstream, interval: Context.SchedulerTimeType.Stride, tolerance: Context.SchedulerTimeType.Stride, scheduler: Context, options: Context.SchedulerOptions? = nil)
```

## Parameters

`upstream`

The publisher from which this publisher receives its elements.

`interval`

The amount of time to delay.

`tolerance`

The allowed tolerance in delivering delayed events. The `Delay` publisher may deliver elements this much sooner or later than the interval specifies.

`scheduler`

The scheduler to deliver the delayed events.

`options`

Options relevant to the scheduler’s behavior.
