根据生日计算年龄

func GetYearDiffer(start_time, end_time string) int {
    var Age int64
    var pslTime string
    if strings.Index(start_time, ".") != -1 {
        pslTime = "2006.01.02"
    } else if strings.Index(start_time, "-") != -1 {
        pslTime = "2006-01-02"
    } else {
        pslTime = "2006/01/02"
    }
    t1, err := time.ParseInLocation(pslTime, start_time, time.Local)
    t2, err := time.ParseInLocation("2006-01-02", end_time, time.Local)

    if err == nil && t1.Before(t2) {
        diff := t2.Unix() - t1.Unix()
        Age = diff / (3600 * 365 * 24)
        return int(Age)
    } else {
        return int(Age)
    }
}
