var WallClock wallClock

    WallClock exposes wall-clock time via the Clock interface.


    func Alarm

    func Alarm(c Clock, t time.Time) <-chan time.Time

      Alarm returns a channel that will have the time sent on it at some point after the supplied time occurs.

      This is short for c.After(t.Sub(c.Now())).


      type Clock

      type Clock interface {
      	// Now returns the current clock time.
      	Now() time.Time
      	// After waits for the duration to elapse and then sends the
      	// current time on the returned channel.
      	After(time.Duration) <-chan time.Time
      	// AfterFunc waits for the duration to elapse and then calls f in its own goroutine.
      	// It returns a Timer that can be used to cancel the call using its Stop method.
      	AfterFunc(d time.Duration, f func()) Timer
      	// NewTimer creates a new Timer that will send the current time
      	// on its channel after at least duration d.
      	NewTimer(d time.Duration) Timer

        Clock provides an interface for dealing with clocks.

        type Timer

        type Timer interface {
        	// When the Timer expires, the current time will be sent on the
        	// channel returned from Chan, unless the Timer was created by
        	// AfterFunc.
        	Chan() <-chan time.Time
        	// Reset changes the timer to expire after duration d.
        	// It returns true if the timer had been active, false if
        	// the timer had expired or been stopped.
        	Reset(time.Duration) bool
        	// Stop prevents the Timer from firing. It returns true if
        	// the call stops the timer, false if the timer has already expired or been stopped.
        	// Stop does not close the channel, to prevent a read
        	// from the channel succeeding incorrectly.
        	Stop() bool

          The Timer type represents a single event. A Timer must be created with AfterFunc. This interface follows time.Timer's methods but provides easier mocking.
