Active Directory Strange Attribute Value

I'm getting info about a user in Active Directory using this code:

    SearchResultCollection searchResults = null;
    string activeDirFilter = getActiveDirFilter();
    DirectoryEntry dirEntry = new DirectoryEntry();

    DirectorySearcher searcher = new DirectorySearcher(dirEntry)
    {
        PageSize = 100,
        Filter = activeDirFilter,
        SearchScope = SearchScope.Subtree
    };

This code works fine and I'm getting these attributes:

LASTLOGON
130388757393977187

PWDLASTSET
130378422326246669

LASTLOGONTIMESTAMP
130380275331980403

However, I can't make sense of the value, does anyone know how to decode those numbers to time stamps?

EDIT: The values can't be seconds since epoch, because 130388757393977187 seconds = 4 131 858.64 millenniums.

It can't be ticks either, because 130388757393977187 = 413 years.

I worked it out:

You need to use

long x = 130388757393977187;
DateTime dateTime = DateTime.FromFileTimeUtc(x);

You currently have the Unix Timestamp you should convert it into DateTime object and print it.

public static DateTime UnixTimeStampToDateTime(double unixTimeStamp)
{
    // Unix timestamp is seconds past epoch
    System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
    dtDateTime = dtDateTime.AddSeconds(unixTimeStamp).ToLocalTime();
    return dtDateTime;
}
