Timestamp from LDAP (ActiveDirectories lastLogonTimestamp)

Timestamp from LDAP (ActiveDirectories lastLogonTimestamp)

• Brent Mullet

  Hi
  
  lastLogonTimeStamp seems to be the no of 100 nano second intervals starting from 0000 hrs 1/1/1601.
  
  This is similiar to windows file time format and .NET has support to create a System.DateTime object out of this value.. Note the sample here, using the long value that you had provided and watch the date being recreated..
  
  .NET Sample :
  import System.*;
  class Test
  {
  public static void main(String args[])
  
  {
  DateTime dt=DateTime.FromFileTime(127877417297554938L);
  System.out.println(dt);
  }
  }
  
  Java Sample :
  If you want to create a java date object out of this value, please try following this sample, where i have used an adjustment factor to convert the lastLogonTimestamp value into a Date object..
  
  import java.util.*;
  class Test
  {
  public static void main(String args[])
  {
  
  long llastLogonAdjust=11644473600000L; // adjust factor for converting it to java
  //date Epoch
  Date lastLogon = new Date(127877417297554938L/10000-llastLogonAdjust); //
  System.out.println(lastLogon);
  }
  }
  
  Thanks
  
  With regards
