时间戳 日期 转换

时间戳转日期

 		public static DateTime GetDateTime(long timeStamp)
        {
            DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
            long lTime = timeStamp * 10000000;
            TimeSpan toNow = new TimeSpan(lTime);
            DateTime targetDt = dtStart.Add(toNow);
            return targetDt;
        }

日期转时间戳

		public static long GetTimestamp(DateTime d)
        {
            TimeSpan ts = d.ToUniversalTime() - new DateTime(1970, 1, 1);
            return (long)ts.TotalSeconds;     //精确到毫秒
        }
