GO语言：时间处理

package main

	"time"

	timer1 := time.NewTimer(time.Second * 5)
	<-timer1.C //阻塞，5秒后继续执行
	fmt.Println("wait for timer1")

	go func() {
		<- timer2.C//阻塞，15秒后继续执行
		fmt.Println("wait for timer2")
	}()
	
	stop2 := timer2.Stop()//取消timer2的阻塞
	if stop2 {
		fmt.Println("timer2 end")
	}
}

package main

	time.Sleep(time.Second * 20)
	ticker.Stop()
