golang date to time

With the development of the times, computer languages ​​are constantly updated and developed. Among them, golang, as an emerging programming language, is loved by developers for its rapid development and efficient performance. In golang, converting date to time is a common requirement, and it is also a relatively complex issue in development. So, how to convert date to time in golang? This article will introduce in detail the methods and techniques of converting date to time in golang.

1. Basic knowledge of golang date to time conversion

In golang, date and time are implemented through the time package. In this package, the most basic is the time.Time type, which represents a point in time and a time zone. This type contains a Unix timestamp, which is the number of seconds from UTC (Greenwich Mean Time) on January 1, 1970 to the current point in time, and a time zone information. Therefore, we can convert date to time through Unix timestamp.

2. Implementation method of converting date to time in golang

In golang, the basic method of converting date to time is to convert the date to a Unix timestamp, and then use the time.Unix function to convert the Unix timestamp Convert to time of type time.Time, and finally use the Format method of this type to format the time into the specified format. Let's take a look at the specific implementation method.

1. Convert date to Unix timestamp
   In golang, we can use the Parse function in the time package to convert the date string into a time of type time.Time, and then use the Unix function to Convert it to Unix timestamp. An example is as follows:

package main

import (
    "fmt"
    "time"
)

func main() {
    dateStr := "2022-10-10 10:10:10"
    loc, _ := time.LoadLocation("Local")
    date, _ := time.ParseInLocation("2006-01-02 15:04:05", dateStr, loc)
    unixTime := date.Unix()
    fmt.Println(unixTime) // 输出: 1665425410
}

In the above example, we defined a date string and a location in the local time zone. Next, use the time.ParseInLocation function to convert the date string to a time of type time.Time, and use the Unix function to convert the time to a Unix timestamp. Finally, we output the Unix timestamp to the console.

2. Convert Unix timestamp to time.Time type time
   In golang, we can use the Unix function in the time package to convert Unix timestamp to time.Time type time. An example is as follows:

package main

import (
    "fmt"
    "time"
)

func main() {
    unixTime := int64(1665425410)
    date := time.Unix(unixTime, 0)
    fmt.Println(date) // 输出: 2022-10-10 10:10:10 +0800 CST
}

In the above example, we defined a Unix timestamp and a time of type time.Time. Next, use the time.Unix function to convert the Unix timestamp to a time of type time.Time, and finally output it to the console.

3. Format the time of type time.Time into the specified format
   In golang, we can use the Format method of type time.Time to format the time into the specified format. An example is as follows:

package main

import (
    "fmt"
    "time"
)

func main() {
    dateStr := "2022-10-10 10:10:10"
    loc, _ := time.LoadLocation("Local")
    date, _ := time.ParseInLocation("2006-01-02 15:04:05", dateStr, loc)
    formatStr := "2006年01月02日 15点04分05秒"
    dateStr2 := date.Format(formatStr)
    fmt.Println(dateStr2) // 输出: 2022年10月10日 10点10分10秒
}

In the above example, we define a date string, a local time zone location and a date format string. Next, use the time.ParseInLocation function to convert the date string to a time of type time.Time, and then use the format string to format the time into the specified format. Finally, the formatted date string is output to the console.

3. Summary

Through the introduction of this article, we can understand the methods and techniques of how to convert date to time in golang. Simply put, we can convert the date to a Unix timestamp, then convert it to a time of type time.Time, and use the Format method of this type to format the time into the specified format. It is worth noting that when converting date to time, we need to set the format and time zone information of the date string in order to correctly convert it to Unix timestamp and time.Time type time.
