Get the current time using the time.Now function in the Go language documentation

Title: Example of using Go language to get the current time

Text:

Go language is a programming language known for its simplicity and efficiency. , which provides a rich standard library that makes daily coding tasks easy and enjoyable. Among them, the time package is a very useful standard library provided by the Go language, which can help us handle and operate time-related tasks.

In this article, we will learn how to use the time.Now function of Go language to get the current time example. The following is the specific code implementation:

package main

import (
    "fmt"
    "time"
)

func main() {
    // 调用Now函数获取当前的时间对象
    currentTime := time.Now()

    // 使用Format函数将时间对象格式化为指定的字符串
    formattedTime := currentTime.Format("2006-01-02 15:04:05")
    
    // 输出格式化后的时间字符串
    fmt.Println("当前时间为：", formattedTime)
}

Code explanation:

First, we imported fmt and time# through the import statement ##These two packages. Then, in the main function, we call the time.Now() function to get the current time object and assign it to the currentTime variable.

Next, we use the

Format function to format the time object currentTime into the specified string"2006-01-02 15:04:05 ", and assign the formatted time string to the formattedTime variable.

Finally, we print out the formatted time string by calling the

fmt.Println() function.

Run the above code, you will see output similar to the following:

当前时间为： 2021-03-25 10:30:00

It should be noted that,

"2006-01-02 15:04:05" Numbers and delimiters in this time format string are fixed. This is because the time format reference time of Go language is: "2006-01-02 15:04:05". So when formatting time, we need to use this fixed time format string.

Summary:

In this article, we learned how to use the

Now function in the time package of the Go language to get the current time. With the powerful and easy-to-use standard library of Go language, we can easily process and manipulate time, which provides great convenience for our programming work. Hope the above content can be helpful to you!
