Providing a wrong time duration

Mistake

It is not obvious when this ticker will go off. We would assume every second, but in fact it is ever microsecond.

ticker := time.NewTicker(1000)
for {
  select {
  case <-ticker.C:
    // tick
  }
}

Using the time durations provided from the time package we can be certain how this ticker works.

ticker := time.NewTicker(time.Second)
for {
  select {
  case <-ticker.C:
    // tock
  }
}
