What is time.Now() Function in Golang

by

The time.Now() is a built-in function in Go (Golang) that returns the current local time. The function returns a time.Time value represents the current point in time, including the current date and time down to nanosecond precision.

Syntax

func Now() Time

Return value

It returns the current local time.

Example 1

To use the time.Now() function, you need to import the time package first.

package main

import (
  "fmt"
  "time"
)

func main() {
  currentTime := time.Now()
  fmt.Println("The current time is:", currentTime)
}

Output

The current time is: 2023-03-17 19:37:10.097827 +0530 IST m=+0.000182710

In this example, we import the time package and then call time.Now() to get the current time. The result is stored in the currentTime variable, which is then printed to the console.

Example 2

To get the year, month, day, hour, minute, second, and nanosecond individually in Golang, you can use the time.Now() function.

package main

import (
  "fmt"
  "time"
)

func main() {
  currentTime := time.Now()
  
  fmt.Println("Year:", currentTime.Year())
  fmt.Println("Month:", currentTime.Month())
  fmt.Println("Day:", currentTime.Day())
  fmt.Println("Hour:", currentTime.Hour())
  fmt.Println("Minute:", currentTime.Minute())
  fmt.Println("Second:", currentTime.Second())
  fmt.Println("Nanosecond:", currentTime.Nanosecond())
}

Output

Year: 2023
Month: March
Day: 17
Hour: 19
Minute: 42
Second: 57
Nanosecond: 70569000

That’s it.
