time.Nanoseconds() Function in Golang With Examples

In Go language, time packages supplies functionality for determining as well as viewing time. The Nanoseconds() function in Go language is used to find the duration of time in form of an integer nanosecond count. Moreover, this function is defined under the time package. Here, you need to import the “time” package in order to use these functions.

Syntax:

func (d Duration) Nanoseconds() int64

Here, d is the duration of time.

Return Value: It returns the duration value as int64.

Example 1:

// Golang program to illustrate the usage of
// Nanoseconds() function

// Including main package
package main

// Importing fmt and time
import (
    "fmt"
    "time"
)

// Calling main
func main() {

    // Defining duration
    // of Nanoseconds method
    nano, _ := time.ParseDuration("8s")

    // Prints duration as int64
    fmt.Printf("Only %d nanoseconds of"+
     " task is remaining.", nano.Nanoseconds())
}

Output:

Only 8000000000 nanoseconds of task is remaining.

Example 2:

// Golang program to illustrate the usage of
// Nanoseconds() function

// Including main package
package main

// Importing fmt and time
import (
    "fmt"
    "time"
)

// Calling main
func main() {

    // Defining duration of Nanoseconds method
    nano, _ := time.ParseDuration("56m7855s576567576ms")

    // Prints duration as int64
    fmt.Printf("Only %d nanoseconds of task"+
       " is remaining.", nano.Nanoseconds())
}

Output:

Only 587782576000000 nanoseconds of task is remaining.
