Golang 处理夏令时取巧的方法

import (
    "fmt"
    "time"
)

func main() {
    now = time.Now().Unix()
    mTmZone := int64(1)
    timeFormat := LocalTime(now, mTmZone).Format("2006-01-02 15:04:05")

    loc, err := time.LoadLocation("Europe/Malta")
    fmt.Println(loc, err)

    testz, _ := time.ParseInLocation("2006-01-02 15:04:05", timeFormat, loc)

    if (testz.Hour()+24-testz.UTC().Hour())%24 > mTmZone { //这个时候时间正偏移， 带夏令时
        diff := (testz.Hour()+24-testz.UTC().Hour())%24 - mTmZone
        testz = jojoTime.LocalTime(now+int64(diff*3600), mTmZone)        
    }

    fmt.Println(testz.Format("2006-01-02 15:04:05"))
}

//diff为标准时区
func LocalTime(tm int64, diff int64) time.Time {
    //这里固定本机系统时间的时区为 Asia/Shanghai +8区
    if tm > 9999999999 {
        //毫秒
        tm = tm / 1000
    }

    var locTm int64
    if diff == 8 {
        locTm = tm
    } else if diff < 8 {
        locTm = tm - (8-diff)*3600
    } else {
        locTm = tm + (diff-8)*3600
    }
    return time.Unix(locTm, 0)
}
