如何使用Unity時間戳

publicstatic string getTime(string_time)   
  { 
    stringtimeStamp = _time;   
    DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(newDateTime(1970, 1, 1));   
    longlTime = long.Parse(timeStamp + "0000000");   
    TimeSpan toNow = newTimeSpan(lTime);    
    DateTime dtResult = dtStart.Add(toNow); 
    Debug.Log(dtResult);
    stringdate = dtResult.ToShortDateString().ToString(); 
    stringtime = dtResult.ToLongTimeString().ToString(); 
    string[] date_arr = date.Split('/');  
    string[] time_arr = time.Split(':');  
    stringresult = date_arr[0]+"月"+date_arr[1]+"日"+" "+time_arr[0]+"時"+time_arr[1]+"分";      
    returnresult;  
  }

publicstring DateStringFromNow(stringdt) 
  {
    stringtimeStamp = dt;   
    DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(newDateTime(1970, 1, 1));   
    longlTime = long.Parse(timeStamp + "0000000");   
    TimeSpan toNow = newTimeSpan(lTime);    
    DateTime dtResult = dtStart.Add(toNow); 
    TimeSpan span = DateTime.Now - dtResult; 
    if(span.TotalDays > 90) 
    {
      return"3個月前";
 
    }
    else
    if(span.TotalDays > 60) 
    {
      return"2個月前";
 
    }
    elseif ( span.TotalDays > 30 ) 
    {
       
      return"1個月前";
    }
    elseif (span.TotalDays > 14) 
    {
      return
        "2周前";
    }
    elseif (span.TotalDays > 7) 
    {
      return"1周前";
    }
     
    elseif (span.TotalDays > 1) 
    {
      returnstring.Format("{0}天前",
                 (int)Math.Floor(span.TotalDays));
    }
    elseif (span.TotalHours > 1) 
    {
      returnstring.Format("{0}小時前", (int)Math.Floor(span.TotalHours));
    }
    elseif (span.TotalMinutes > 1) 
    {
      returnstring.Format("{0}分鐘前", (int)Math.Floor(span.TotalMinutes));
    }
    elseif (span.TotalSeconds >= 1) 
    {
      returnstring.Format("{0}秒前",
                 (int)Math.Floor(span.TotalSeconds));
    }
     
    else{ 
      return"1秒前";
       
    }
}
