## Topics

### Getting Well-Known Times

[`now()`](/documentation/Dispatch/DispatchTime/now())

Returns the current time.

[`distantFuture`](/documentation/Dispatch/DispatchTime/distantFuture)

A time in the distant future.

### Creating a Dispatch Time Object

[`init(uptimeNanoseconds:)`](/documentation/Dispatch/DispatchTime/init(uptimeNanoseconds:))

Creates a time relative to the amount of time the system has been running.

### Getting the Time

[`rawValue`](/documentation/Dispatch/DispatchTime/rawValue)

Returns the underlying time value.

[`uptimeNanoseconds`](/documentation/Dispatch/DispatchTime/uptimeNanoseconds)

Returns the number of nanoseconds since boot, excluding any time the system spent asleep.

### Modifying the Value

[`advanced(by:)`](/documentation/Dispatch/DispatchTime/advanced(by:))

[`distance(to:)`](/documentation/Dispatch/DispatchTime/distance(to:))
