golang time to string

In recent years, Golang has received more and more attention and love from developers. As a relatively new programming language, Golang has many trendy features and advantages, among which time format processing is favored by developers.

In Golang, the way of time processing is quite flexible, and you can use the time package in the standard library to perform various time operations. Moreover, the time package in Golang also provides a convenient time formatting method, allowing the time type to be converted to a string type.

Below, we will discuss how to convert the time type in Golang to a string type.

Method of converting time type to string type

In Golang, there are two important time types: time.Time and time.Duration. The time.Time type represents an absolute time, and the time.Duration type represents the length of a period of time. We mainly discuss here how to convert the time.Time type to a string type.

The time.Time type has a method called Format, which can convert the time type into a string type in a specified format. The format consists of a series of formatting characters.

The following are common formatting characters and their meanings:

• 2006-01-02 15:04:05.999999999 -0700 MST: Complete date and time (RFC3339)
• 01/02 15:04:05: Date and time in US format
• Mon Jan 2 15:04:05 -0700 MST 2006: Date and time in ANSIC format
• 2006-01-02: Date

When using the Format method, we pass the format string as a parameter to the method. For example, assuming we want to convert the current time to a string in RFC3339 format, we can use the following code:

currentTime := time.Now()
formattedTime := currentTime.Format(time.RFC3339)
fmt.Printf("formattedTime: %s
", formattedTime)

In the above code, we called the time.Now() method to obtain the current time. Then, the Format method is called using this time, and the RFC3339 time format is specified.

The results are as follows:

formattedTime: 2022-05-28T16:40:11+08:00

It should be noted that the order of time formatting must be in accordance with the order of standard formatting characters, otherwise the conversion will fail.

Sample code to convert time type to string type

Next, we will demonstrate a simple sample code to convert time type to string type:

package main

import (
    "fmt"
    "time"
)

func main() {
    currentTime := time.Now()
    formattedTime := currentTime.Format("2006-01-02 15:04:05")
    fmt.Printf("formattedTime: %s
", formattedTime)
}

In the above code, we used time.Now() to obtain the current time, and called the Format method to convert the time into a string type in the specified format. Finally, we use the fmt.Printf() method to print the formatted time.

The output results are as follows:

formattedTime: 2022-05-28 16:40:11

Summary

In Golang, it is very convenient to use the Format method of the time package to convert the time type into a string type. We only need to specify the corresponding formatting characters.

In addition, in time processing, we need to pay special attention to the order of formatting characters and the time zone issue of the time, otherwise it will easily lead to time conversion failure. Therefore, in practice, we need to carefully think and verify the correctness of time formatting to avoid unnecessary errors.
