C#获取时间戳的几种方式

            Console.WriteLine(Convert.ToDouble(DateTime.UtcNow.Ticks - 621355968000000000) / (10 * 1000 * 1000));
            TimeSpan ts1 = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0);
            TimeSpan ts2 = new TimeSpan(DateTime.Now.ToUniversalTime().Ticks - 621355968000000000);
            TimeSpan ts3 = new TimeSpan(DateTime.UtcNow.Ticks - 621355968000000000);
            Console.WriteLine(ts1.TotalSeconds);
            Console.WriteLine(ts2.TotalSeconds);
            Console.WriteLine(ts3.TotalSeconds);
            Console.ReadLine();
