Timers in Go
by yhuang Go fmt.Println time.NewTimer time.Second fmt time
Timers represent a single event in the future. You tell the timer how long you want to wait, and it provides a channel that will be notified at that time.
package main

import (
    "fmt"
    "time"
)

func main() {

    timer1 := time.NewTimer(2 * time.Second)

    <-timer1.C
    fmt.Println("Timer 1 expired")

    timer2 := time.NewTimer(time.Second)
    go func() {
        <-timer2.C
        fmt.Println("Timer 2 expired")
    }()
    stop2 := timer2.Stop()
    if stop2 {
        fmt.Println("Timer 2 stopped")
    }
}
