时间戳转datetime
timestamp为10位秒级* 10000000，若为13位毫秒级*10000。
private DateTime TimestampToDateTime(long timestamp)
{
DateTime dateTimeStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970,1,1));
long lTime = timestamp * 10000000;
TimeSpan nowTimeSpan = new TimeSpan(lTime);
DateTime resultDateTime = dateTimeStart.Add(nowTimeSpan);
return resultDateTime;
}
DateTime转时间戳
秒级
private int DateTimeToTimestamp(DateTime time)
{
DateTime startDateTime = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(197, 1, 1));
return Convert.ToInt32((time - startDateTime).TotalSeconds);
}
