Converting AD long dates to Java Date format

Environment : OIM 9.0.3, OIM Connector Pack 9.0.4.1, AD 2000

When you reconcile data from AD, the AD dates fail to link up OIM dates because of different format. The dates are stored in AD in long format and OIM uses normal Java Dates. So, here is the code that you can use to make this conversion.

import java.util.Date;
import java.util.TimeZone;
import java.text.SimpleDateFormat;
public class AD
{
public void converADdateToOIMdate(long ADdate){

long ADdate = Long.parseLong(String.valueOf(ADdate));
System.out.println("long value : "+ADdate);

// Filetime Epoch is 01 January, 1601
// java date Epoch is 01 January, 1970
// so take the number and subtract java Epoch:
long javaTime = ADdate - 0x19db1ded53e8000L;

// convert UNITS from (100 nano-seconds) to (milliseconds)
javaTime /= 10000;

// Date(long date)
// Allocates a Date object and initializes it to represent
// the specified number of milliseconds since the standard base
// time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.
Date theDate = new Date(javaTime);


System.out.println("java DATE value : "+theDate);

SimpleDateFormat formatter = new SimpleDateFormat("MMMMM d, yyyy");
// change to GMT time:
//formatter .setTimeZone(TimeZone.getTimeZone("GMT"));

String newDateString = formatter.format(theDate);

System.out.println("Date changed format :" + newDateString);
}


public static void main(String[] args)
{
AD d=new AD();
d.converADdateToOIMdate(128568528000000000L);
// 9223372036854775807
// 127948319499226601
