It's the number of ticks since Jan-01-1601 in UTC, according to Reference, which describes the significance of the year 1601. Good background reading.
var accountExpires = 129508380000000000; var dt = new DateTime(1601, 01, 01, 0, 0, 0, DateTimeKind.Utc).AddTicks(accountExpires);
Original Accepted Answer
It's the number of ticks since Jan-02-1601.
DateTime dt = new DateTime(1601, 01, 02).AddTicks(129508380000000000);

You can use the FromFileTime method on the DateTime class, but watch out, when this field is set to not expire, it comes back as the Int64.MaxValue and doesn't work with either of these methods.
Int64 accountExpires = 129508380000000000; DateTime expireDate = DateTime.MaxValue; if (!accountExpires.Equals(Int64.MaxValue)) expireDate = DateTime.FromFileTime(accountExpires);
Account expires value in LDAP. - MSDN, Visual C#. Visual C# var rootEntry = new DirectoryEntry("LDAP://xxx.com"); How do I get the account expire into a DateTime value? You need to convert it to FILETIME, as per the specification: DateTime dt = DateTime.Now.AddDays(30); long ftAccountExpires = dt.ToFileTime(); In the above example, if you set accountExpires to the value of ftAccountExpires, the account will expire 30 days from now
Some info for anyone who came here looking to set the AccountExpires value.
To clear the expiry is nice and easy:
entry.Properties["accountExpires"].Value = 0;
However if you try to directly write back an int64 / long:
entry.Properties["accountExpires"].Value = dt.ToFileTime();
You can get a 'COMException was unhandled - Unspecified error'
Instead write back the value as a string data type:
entry.Properties["accountExpires"].Value = dt.ToFileTime().ToString();
Be aware of the time of day you are setting, for consistancy with ADUC the time should be 00:00.
Instead of .Now or .UtcNow you can use .Today:
var dt1 = DateTime.Today.AddDays(90); entry.Properties["accountExpires"].Value = dt1.ToFileTime().ToString();
Other input like dateTimePicker you can replace the time, Kind as Local for the Domain Controller:
var dt1 = dateTimePicker1.Value; var dt2 = new DateTime(dt1.Year, dt1.Month, dt1.Day, 0, 0, 0, DateTimeKind.Local); entry.Properties["accountExpires"].Value = dt2.ToFileTime().ToString();

- By the way, it seems to be in UTC time, but you'll want to make sure.
- Thanks very much. I'm wondering why Microsoft made it that difficult for the expire date. Puzzle...
- It is actually the number of ticks since 1601-01-01, not 1601-01-02.
- When I look at Active Directory Users & Computers at the "Account Expires" date, and compare it with this, I need to use 1600-12-30 to make it match. (then again, per the referenced article "It is common for the values to differ by a day, sometimes even two days.")
- Yeah, I noticed that. But I am wondering is there any better or direct way to convert it. Thanks for the advice.
