What is time.Tick() Function in Golang

by

Golang time.Tick() is a “utility wrapper for NewTicker function that allows access to the ticking channel.” Tickers are used to do something frequently at regular intervals of the stated time.

The channel was created over time.Tick() function will continue to tick indefinitely. To release the resources associated with the ticker, consider using time.NewTicker() instead returns a Ticker object you can stop when it’s no longer needed.

Syntax

func Tick(d Duration) <-chan Time

Parameters

It takes a Duration as an argument.

Return value

It returns a receive-only channel (<-chan Time) that sends a Time value at specified intervals.

Example 1

package main

import (
  "fmt"
  "time"
)

func main() {
  tick := time.Tick(1 * time.Second)

  for currentTime := range tick {
    fmt.Println("Current time:", currentTime)
  }
}

Output

Current time: 2023-03-18 01:27:15.817433 +0530 IST m=+1.001282167
Current time: 2023-03-18 01:27:16.817462 +0530 IST m=+2.001326084
Current time: 2023-03-18 01:27:17.817404 +0530 IST m=+3.001282501
Current time: 2023-03-18 01:27:18.817373 +0530 IST m=+4.001267834
Current time: 2023-03-18 01:27:19.817356 +0530 IST m=+5.001264917

Example 2

package main

import (
  "fmt"
  "time"
)

func periodicTask() {
  fmt.Println("Periodic task executed at", time.Now())
}

func main() {
  ticker := time.Tick(2 * time.Second)

  for {
    select {
      case <-ticker:
        periodicTask()
    }
  }
}

Output

Periodic task executed at 2023-03-18 01:35:11.649779 +0530 IST m=+2.001321209
Periodic task executed at 2023-03-18 01:35:13.649864 +0530 IST m=+4.001436834

Periodic task executed at 2023-03-18 01:35:17.64971 +0530 IST m=+8.001343918
