昨天我在這里踩坑了，我用的是格林威治時(shí)間計(jì)算的時(shí)間戳，給計(jì)算機(jī)監(jiān)控系統(tǒng)。計(jì)算機(jī)監(jiān)控系統(tǒng)拿到時(shí)間戳換算后的時(shí)間總是跟我的對(duì)不上。后來發(fā)現(xiàn)是這個(gè)原因；

1.標(biāo)準(zhǔn)時(shí)間轉(zhuǎn)時(shí)間戳的方法

/// <summary>
        /// 獲取開停機(jī)的時(shí)間戳
        /// </summary>
        /// <param name="dtime"></param>
        /// <returns></returns>
        public int getTimeSpan(DateTime dtime)
        {
            //格林威治時(shí)間
            //var timeSpan_Greenwich = dtime - new DateTime(1970, 1, 1, 0, 0, 0);
            //標(biāo)準(zhǔn)北京時(shí)間
            var timeSpan = dtime - new DateTime(1970, 1, 1, 8, 0, 0);
            //或者這樣寫北京標(biāo)準(zhǔn)時(shí)間
            var timeSpan_beijing = dtime - TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1, 0, 0, 0));
           return (int)timeSpan.TotalSeconds;        }

2.時(shí)間戳轉(zhuǎn)為標(biāo)準(zhǔn)時(shí)間

/// <summary>  
        /// 時(shí)間戳Timestamp轉(zhuǎn)換成日期  
        /// </summary>  
        /// <param name="timeStamp"></param>  
        /// <returns></returns>  
        private DateTime GetDateTime(int timeStamp)
        {
            SaveCommand("timeStamp:" + timeStamp);

            DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
            long lTime = ((long)timeStamp * 10000000);
            TimeSpan toNow = new TimeSpan(lTime);
            DateTime targetDt = dtStart.Add(toNow);

            if (string.IsNullOrEmpty(targetDt.ToString()))
            {
                targetDt = DateTime.Now;
            }

            SaveCommand("time:" + targetDt.ToString());

            return targetDt;
        }

3.TimeZone.CurrentTimeZone.ToLocalTime()方法

這個(gè)方法將一個(gè) DateTime 對(duì)象，獲取其值為對(duì)應(yīng)于 time 的本地時(shí)間?？梢钥吹竭@個(gè)方法格林威治的時(shí)間 1970-01-01 00:00:00 轉(zhuǎn)為了北京時(shí)間 1970-01-01 08:00:00
