分享在C#中時間戳記是怎麼轉換的？

時間戳記轉DateTime

timestamp為10位秒級* 10000000，若為13位毫秒級*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轉時間戳記

秒級

private int DateTimeToTimestamp(DateTime time)
{
DateTime startDateTime = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(197, 1, 1));
return Convert.ToInt32((time - startDateTime).TotalSeconds);

}
