Defined in: packages/common/src/Schedule.ts:1121

Outputs the delay between recurrences.

Wraps a schedule to output its delay (in milliseconds) instead of the original output. Useful for monitoring or logging delay patterns.

Example

// Monitor exponential delays
const monitorDelays = delays(exponential("100ms"));
// Outputs: 100, 200, 400, 800, ... (the delays themselves)

// Log delays for debugging
const logged = tapScheduleOutput(console.log)(delays(exponential("100ms")));
