Sleep For A Duration

Many languages allow you to sleep for a certain number of milliseconds. In those languages, you can give 500 or 1000 to the sleep function to sleep for half a second and a second respectively. In Go, the duration of a call to time.Sleep is in nanoseconds. Fortunately, there are constants that make it easy to sleep in terms of milliseconds.

For example, you can sleep for a half a second (500 milliseconds) like so:

package main

import (
    "time"
)

func main() {
    time.Sleep(500 * time.Millisecond)
}

Other available time constants are Nanosecond, Microsecond, Second, Minute, Hour.
