我有一個(gè)沒(méi)有時(shí)區(qū)信息的時(shí)間戳。我需要以“+02:00”格式添加時(shí)區(qū)偏移量。那么在下面的代碼中，如何將偏移變量轉(zhuǎn)換為“+02:00”字符串以便獲得正確的 RFC3339 時(shí)間？func main() {    zone, offset := time.Now().Zone()    fmt.Println("zone :", zone)    fmt.Println("offset :", offset )    logtimestamp := "2020-11-14 05:53:40,103"    logtimestamp = strings.Split(logtimestamp, ",")[0]    logtimestampFields := strings.Fields(logtimestamp)    if len(logtimestampFields) > 1 {        logtimestamp = logtimestampFields[0] + "T" + logtimestampFields[1] + "+02:00" //replace "+02:00" with proper offset here    }        formattedTime, _ := time.Parse(time.RFC3339, logtimestamp)    fmt.Println("formatted timestamp " + formattedTime.Format(time.RFC3339))}
