Golang 时间转换

完整代码

https://github.com/smallinsect/MyGo/tree/master/mytimer

//时间转换的模板，golang里面只能是 "2006-01-02 15:04:05" （go的诞生时间）
var TIME_LAYOUT string = "2006-01-02 15:04:05"

var (
    testTime string = "2020-07-08 10:00:00"
)

Unix()时间戳，和时区无关。

1、字符串转时间，默认UTC

    fmt.Println("==================================")
    start, _ := time.Parse(TIME_LAYOUT, testTime)
    fmt.Println(start)
    fmt.Println(start.Unix())
    fmt.Println(start.UTC())
    fmt.Println(start.UTC().Unix())

 2、字符串转时间，添加时区

    fmt.Println("==================================")
    startT, _ := time.ParseInLocation(TIME_LAYOUT, "2020-03-25 18:00:00", time.Local)
    fmt.Println(startT)
    fmt.Println(startT.Unix())
    fmt.Println(startT.UTC())
    fmt.Println(startT.UTC().Unix())

 3、Now()获取当前系统时区当前时间

    fmt.Println("==================================")
    now := time.Now()
    fmt.Println(now)
    fmt.Println(now.Unix())
    fmt.Println(now.UTC())
    fmt.Println(now.UTC().Unix())

 4、设置现在时间

    fmt.Println("==================================")
    var cstSh, _ = time.LoadLocation("Asia/Shanghai") //上海
    fmt.Println(now.In(cstSh))
    var utcSh, _ = time.LoadLocation("UTC")
    fmt.Println(now.In(utcSh))

 5、时区

    fmt.Println("==================================")
    fmt.Println(time.Now().Zone())
    fmt.Println(time.LoadLocation("Local"))                                //获取时区
    timeStr := time.Now().Format("2006-01-02 15:04:05")                    //转化所需模板
    loc, _ := time.LoadLocation("Local")                                   //获取时区
    fmt.Println(time.ParseInLocation("2006-01-02 15:04:05", timeStr, loc)) //使用模板在对应时区转化为time.time类型
    fmt.Println(time.Local)

 6、Unix时间转时间

    fmt.Println("==================================")
    fmt.Println(now)
    fmt.Println(now.Unix())
    fmt.Println(now.UTC())
    fmt.Println(time.Unix(now.Unix(), 0))           // Unix()转时间，默认当地时间
    fmt.Println(time.Unix(now.Unix(), 0).In(utcSh)) //Unix转时间，设置时区

 7、时间转字符串

    // 时间转字符串

    fmt.Println("==================================")

    lnow := now.Format(TIME_LAYOUT)

    fmt.Println(lnow)

    lnow = now.In(utcSh).Format(TIME_LAYOUT)

    fmt.Println(lnow)
