Timestamp to datetime

The timestamp is a 10-bit second class * 10000000, if it is a 13-bit millisecond-level *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 turn Timestamp

Second level

private int Datetimetotimestamp (DateTime time)
{
DateTime startdatetime = TimeZone.CurrentTimeZone.ToLocalTime (new datetime (197, 1, 1));
Return Convert.ToInt32 ((time-startdatetime). TotalSeconds);

}
