The DelaySubscription operator modifies the source sequence by pausing for the specified duration before subscribing to the original sequence. This has the effect of delaying the start of the sequence by the specified time interval.

DelaySubscription can be used to control the timing of initialization. Note that if a source is hot, delaying the start of the sequence will not preserve past data, since unlike Delay the DelaySubscription operator does not store or have access to any historical data.

Examples

Use DelaySubscription to postpone initialization of an observable sequence.

DelaySubscription Example

Use Delay to access past data from hot sequences or delay notifications of an observable sequence.
