Dispatch represents a point in time relative to the default clock with nanosecond precision. On Apple platforms, the default clock is based on the Mach absolute time unit.

struct DispatchTime
init(uptimeCreates a time relative to the system clock that ticks since boot.
let rawReturns the underlying dispatch value.
var uptimeReturns the number of nanoseconds since boot, excluding any time the system spent asleep.
static let distantReturns a time in the distant future.
static func now() -> DispatchReturns the current time.
static func != (DispatchReturns a Boolean value indicating whether two values are not equal.
static func ... (DispatchReturns a partial range extending upward from a lower bound.
static func ... (DispatchReturns a partial range up to, and including, its upper bound.
static func ... (DispatchReturns a closed range that contains both of its bounds.
static func ..< (DispatchReturns a partial range up to, but not including, its upper bound.
static func ..< (DispatchReturns a half-open range that contains its lower bound but not its upper bound.
static func <= (DispatchReturns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func > (DispatchReturns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (DispatchReturns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
Base time constants.
struct DispatchDispatch represents an absolute point in time according to the wall clock with microsecond precision. On Apple platforms, the default clock is based on the result of gettimeofday(2).
enum DispatchDispatch represents a number of seconds, millisconds, microseconds, or nanoseconds. You use Dispatch values to specify the interval at which a Dispatch fires or I/O handlers are invoked for a Dispatch channel, as well as to increment and decrement Dispatch values.
enum DispatchDispatch indicates whether a dispatch operation finised before a specified time.
typealias dispatchA somewhat abstract representation of time.
