golang time to int

Go language is a programming language that supports high concurrency and high performance. It provides many powerful tools and libraries so that developers can write efficient and concise code. In the Go language, time processing is also very convenient, and time can be easily converted into an integer.

Generally, we often need to convert time into an integer, which can be achieved in two ways: Unix timestamp and nanosecond timestamp.

Unix timestamp refers to the integer value of seconds, the number of seconds from January 1, 1970 to the present. It is a time zone independent time representation method. Converting time to Unix timestamp can be achieved using the time_unix() function in Go language.

Code example:

package main

import (
    "fmt"
    "time"
)

func main() {

    // 将时间转换为Unix时间戳
    t := time.Date(2021, time.January, 1, 1, 0, 0, 0, time.UTC)
    ts := t.Unix()

    // 输出Unix时间戳
    fmt.Println(ts)
}

The output result is "1609430400", which is the number of seconds from January 1, 1970 to January 1, 2021.

Nanosecond timestamp is a more precise way of expressing time. It refers to the number of nanoseconds since 0:00:00 on January 1, 1970. Converting time to nanosecond timestamp can be achieved using the time_unixNano() function in Go language.

Code example:

package main

import (
    "fmt"
    "time"
)

func main() {

    // 将时间转换为纳秒时间戳
    t := time.Date(2021, time.January, 1, 1, 0, 0, 0, time.UTC)
    ts := t.UnixNano()

    // 输出纳秒时间戳
    fmt.Println(ts)
}

The output result is "1609430400000000000", which is from 0:00:0 on January 1, 1970 to 0:0:0 on January 1, 2021 The number of nanoseconds in seconds.

Summary:

In the Go language, the conversion between time and integer is very convenient and can be achieved through the time_unix() and time_unixNano() functions. We can choose the appropriate method according to our own needs to convert time into an integer to facilitate the implementation of various functions.
