How to adjust time zone in Golang?

How to adjust time zone in Go? Use time.LoadLocation to load the time zone. Use the In method to convert a time to a specified time zone. Use the Format method to format the time into a string. Use the Parse method to parse a time string with time zone information. Get the client time zone in the HTTP request via Header.Get("TimeZone").
#How to adjust time zone in Go?
Preface
In distributed system development, dealing with time zones is very important and the correct time needs to be displayed based on the time zone of the client or server. This article will introduce how to use the time package built into the Go language to adjust the time zone.
Code Examples
The following are several code examples that demonstrate how to set and adjust time zones in Go:
1. Get the current Time zone
// 獲取當前時區(qū)
location, err := time.LoadLocation("Local")
if err != nil {
// 處理錯誤
}2. Set time zone
// 設置時區(qū)為 UTC
location, err := time.LoadLocation("UTC")
if err != nil {
// 處理錯誤
}3. Convert time
// 當前時間轉(zhuǎn)換為 UTC 時區(qū) now := time.Now() nowUTC := now.In(location)
4. Format time string
// 在 UTC 時區(qū)內(nèi)使用 RFC 3339 格式化時間字符串 rfc3339 := nowUTC.Format(time.RFC3339)
5. Parse string based on time zone
// 解析時區(qū)為 UTC 的 RFC 3339 格式時間字符串
t, err := time.ParseInLocation("2006-01-02T15:04:05Z07:00", "2023-02-28T10:00:00Z", time.UTC)
if err != nil {
// 處理錯誤
}Practical case
In actual development, you can use the Header.Get("TimeZone") field in http.Request to obtain the client's preferred time zone, and then use time.LoadLocation Load the corresponding time zone and convert the time.
// HTTP 控制器方法
func ServeTime(w http.ResponseWriter, r *http.Request) {
// 獲取客戶端首選時區(qū)
timeZone := r.Header.Get("TimeZone")
// 加載時區(qū)
location, err := time.LoadLocation(timeZone)
if err != nil {
// 處理錯誤
}
// 獲取當前時間并轉(zhuǎn)換到客戶端時區(qū)
now := time.Now().In(location)
fmt.Fprintf(w, "Current time in your time zone: %s", now.Format(time.RFC3339))
