为什么不能time.In（）在美国/纽约时区中获得正确的时间

Question

Here is my code

package main

import (
  "fmt"
  "time"
)

func main() {
  tz := "America/New_York"
  loc, err := time.LoadLocation(tz)
  if err != nil {
    fmt.Println(err)
  }

  fmt.Println(time.Now().In(loc))
}

And it supposed to get the result like this The Go Playground

2009-11-10 18:00:00 -0500 EST

The weird thing is that it prints out the UTC time instead of EST when trying to run it on my server

Answer 1

It turns out that the system tzdata package is out of date

sudo yum update tzdata

This command fixed the problem, as suggested by @Adrian
