time.Ticker in Go

The time.Ticker type in Go is incredibly useful for situations in which polling is needed.

The easiest way to use the Ticker is via the time.Tick function, which just provides access to the ticking channel, which makes it easy to range over:

package main

import (

func main() {
	for currentTime := range time.Tick(time.Second) {
		fmt.Println("current time: ", currentTime)

For more control, time.NewTicker works wonders - there's no better example than the one from the docs!
