Tickers

Context

A time.Ticker sends periodic events on its channel. Use Stop() to stop the ticker and release resources.

Example

Create a ticker that ticks every 500ms.

Code example

package main

import (
    "fmt"
    "time"
)

func main() {
    ticker := time.NewTicker(500 * time.Millisecond)
    done := make(chan bool)

    go func() {
        for i := 0; i < 3; i++ {
            fmt.Println(<-ticker.C)
        }
        done <- true
    }()

    <-done
    ticker.Stop()
    fmt.Println("Ticker stopped")
}

Output (example timestamps vary)

2025-01-01 12:00:00.123 +0000 UTC
2025-01-01 12:00:00.623 +0000 UTC
2025-01-01 12:00:01.123 +0000 UTC
