Time in active directory is stored in a 64 bit integer that keeps track of
the number of 100-nanosecond intervals which have passed since January 1,
1601. The 64-bit value uses 2 32 bit parts to store the time. The following
is a function that returns the time in the typical format the python time
libraries use (seconds since 1970). Here's an example where you'd use it:
user=opends('fred') print 'time in
seconds',conv_time(user.pwdLastSet.lowpart,user.pwdLastSet.highpart)
user.pwdLastSet returns a com object, not a python data type.
def conv_time(l,h):
#converts 64-bit integer specifying the number of 100-nanosecond
#intervals which have passed since January 1, 1601.
#This 64-bit value is split into the
#two 32 bits stored in the structure.
d=116444736000000000L #diference between 1601 and 1970
#we divide by 10million to convert to seconds
return (((long(h)<< 32) + long(l))-d)/10000000

Subject: RE: Last Logon Date of AD users
Naresh, I received the same information when I ran a script similar to what
you have. However, I am assuming the output with 1/1/1601 is an indication
that they have not logged on to the network. The accounts with the date of
1/1/1601 where alias accounts and accounts we created that have not logged
onto the network.
Maybe someone else can provide additional information as to why the date is
populated with 1/1/1601.

Subject: Last Logon Date of AD users
Hello Everybody,
I am badly in need of help. I need to retrive the last logon date for
specified members. I googled for that and got the below lines from microsoft
On Error Resume Next
Set objUser = GetObject("LDAP://cn=Ken Myer, ou=Finance, dc=fabrikam,
dc=com")
Set objLastLogon = objUser.Get("lastLogonTimestamp")
intLastLogonTime = objLastLogon.HighPart * (2^32) + objLastLogon.LowPart
intLastLogonTime = intLastLogonTime / (60 * 10000000)
intLastLogonTime = intLastLogonTime / 1440
Wscript.Echo "Last logon time: " & intLastLogonTime + #1/1/1601#
I had made changes to the second line according to my OU structure and got
the output : Last logon time: 1/1/1601
Can anyone please help me on this.
Thanks in advance
Naresh
