Use the time.Now function to get the current time

Use the time.Now function to get the current time

In the Go programming language, we can use the Now function in the time package to get the current time. The time.Now function returns a time.Time type value that contains the current date and time information.

The following is a sample code that demonstrates how to use the time.Now function to get the current time and output the result:

package main

import (
    "fmt"
    "time"
)

func main() {
    // 使用time.Now函数获取当前时间
    currentTime := time.Now()

    // 格式化输出当前时间
    fmt.Println("当前时间：", currentTime.Format("2006-01-02 15:04:05"))
}

In the above code, we obtain the current time by calling the time.Now function The current time and assign the returned time.Time type value to the variable currentTime. Then, we can use the currentTime method to access time information such as year, month, day, hour, minute, and second.

In order to output the time in a specific format, we use the Format method of currentTime and pass in a format string "2006-01-02 15:04:05". This time format string is a common writing method in the Go language. The numbers in it represent the sequence of year, month, day, hour, minute and second.

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

当前时间： 2021-05-18 09:45:12

It is worth noting that the time.Now function returns the local time of the current machine. If you need to get the current time in other time zones, you can use the LoadLocation function and In method in the time package to achieve this.

By using the time.Now function, we can easily obtain the current time and perform corresponding processing in the code. In actual development, this function can often be used to record logs, calculate the running time of the program, determine whether the task has timed out, etc. No matter what field we are in, time is a very important concept. Mastering the method of time processing will improve our programming efficiency and code quality.
