go的timer和ticker

package main

import (
        // "fmt"

		"time"
		"log"
)


func main() {

        d := time.Duration(time.Second)

        t := time.NewTicker(d)
        // t := time.NewTimer(d)
        defer t.Stop()

        for {
                <- t.C

				log.Println("timeout...")
				time.Sleep(time.Second*5)
		// need reset
		// t.Reset(time.Second*2)
        }
}
