Working:

    string[] filesPath = Directory.GetFiles(Server.MapPath("~/txtPath/"));        
    foreach (string path in filesPath)
    {
        FileInfo fi = new FileInfo(path);      //This Is Working
       string LastAcceTime = fi.LastWriteTime; //Return Correct Value
    }

Not Working:

    string[] filesPath = Directory.GetFiles(Server.MapPath("~/txtPath/"));        
    foreach (string path in filesPath)
    {
        FileInfo fi = new FileInfo(Server.MapPath(path));  //This Is Worng
       string LastAcceTime = fi.LastWriteTime;             //Return 1/1/1601 
    }

Dont use Server.Mappath twice
