How to get the number of seconds since the epoch using syscall in Golang?

Here, we will learn to get the number of seconds since the epoch using syscall in Golang.

In the Go programming language, to get the number of seconds since the epoch using syscall – we use the Gettimeofday() function of the syscall package. The Gettimeofday() function returns the number of seconds and microseconds since the epoch.

Syntax:

func Gettimeofday(tv *Timeval) (err error)

Consider the below example demonstrating how to get the number of seconds since the epoch using syscall in Golang?

package main

import (
	"fmt"
	"syscall"
	"time"
)

func main() {
	var TimeValue syscall.Timeval
	if err := syscall.Gettimeofday(&TimeValue); err != nil {
		fmt.Printf("Error: %v", err)
	}

	// Printing the seconds & micro seconds
	fmt.Println("Seconds: ", TimeValue.Sec)
	fmt.Println("Micro:   ", TimeValue.Usec)

	// Calculate & Print the Current Date & Time
	// Using the seconds & micro seconds
	fmt.Println(time.Unix(TimeValue.Sec, TimeValue.Usec))
}

Output

Seconds:  1636704620
Micro:    779023
