通过设置本地全局设置时区

Question

Related to Setting timezone globally in golang

In zoneinfo.go you can find the following

// Local represents the system's local time zone.
var Local *Location = &localLoc

wich suggest that you have a global modifiable Local, and you can set it. By setting it, should it have effect to timezones?

Answer 1

Setting time.Local does have an effect on the time local time zone.

For example,

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now().Round(0)
    fmt.Println(now, time.Local)

    loc, err := time.LoadLocation("America/Atka")
    if err != nil {
        fmt.Println(err)
        return
    }
    time.Local = loc

    now = time.Now().Round(0)
    fmt.Println(now, time.Local)
}

Output:

2019-07-16 10:45:41.263418395 -0400 EDT Local
2019-07-16 05:45:41.263530699 -0900 HDT America/Atka
