golang的時區轉換

一、代碼

package main

import (
    "fmt"
    "time"
)

const TIME_LAYOUT = "2006-01-02 15:04:05"

func parseWithLocation(name string, timeStr string) (time.Time, error) {
    locationName := name
    if l, err := time.LoadLocation(locationName); err != nil {
        return time.Time{}, err
    } else {
        //轉成帶時區的時間
        lt, _ := time.ParseInLocation(TIME_LAYOUT, timeStr, l)
        //直接轉成相對時間
        fmt.Println(time.Now().In(l).Format(TIME_LAYOUT))
        return lt, nil
    }
}
func testTime() {
    str:=time.Now().Format("2006-01-02 15:04:05")
    //指定時區
    t1,err:=parseWithLocation("America/Cordoba", str)
    if err !=nil{
        fmt.Println(err)
    }
    fmt.Println(t1)

    t2,err:=parseWithLocation("Asia/Shanghai", str)
    if err !=nil{
        fmt.Println(err)
    }
    fmt.Println(t2)

    t3,err:=parseWithLocation("Asia/Chongqing", str)
    if err !=nil{
        fmt.Println(err)
    }
    fmt.Println(t3)
}

func main() {
    testTime()
}
