golang中使用parse将字符串格式化。但parse返回的是UTC的时间。当我将其转换成时间戳的时候快了8h，这不是我想要的结果。
这需要使用func ParseInLocation(layout, value string, loc *Location) (Time, error)函数格式化成本地时区时间。

package main

import (
	"fmt"
	"time"
)

func main() {

	dateStr := "2015-12-14 00:00:00"
	timestamp1, _ := time.Parse("2006-01-02 00:00:00", dateStr)
	timestamp2, _ := time.ParseInLocation("2006-01-02 00:00:00", dateStr, time.Local)

	fmt.Println(time.Local)

	fmt.Println(timestamp1, timestamp2) //2015-12-14 00:00:00 +0000 UTC         2015-12-14 00:00:00 +0800 CST

	fmt.Println(timestamp1.Unix(), timestamp2.Unix()) //1450051200          1450022400

	fmt.Println("hello wordl")
}
