How to convert AD accountexpires in Local timezone format

Hello Everyone,

In my current project IDM 7.2 SP10, we are reading accountexpires attribute from AD and then converting it to a readable format using uInt8ToDate function.

This function is converting the date in readable GMT format while client want it in local time. While searching SCN, I got below post which says that "True" switch is not working in uInt8ToDate function and even I observed the same.

Can anyone guide how can I convert the date in local timezone. I tried to use getTimezoneOffset() but it thrown error. Any help with the JavaScript formula will be appreciated.

    Hello C Kumar,

    I use this script to retrieve the accountExpires from AD and set it to the local validto attribute for AD:

    var MSTimestamp = Par;
    var MSTimestampNormalized = (MSTimestamp - 116444736000000000 - 864000000000) / 10000;
    var date = new Date(MSTimestampNormalized);
    var MonthValue = new Array("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12");
    var dayOfMonth = '' + date.getDate();
    if (dayOfMonth.length == 1) { dayOfMonth = "0" + dayOfMonth; }
    return date.getFullYear() + "-" + MonthValue[date.getMonth()] + "-" + dayOfMonth;

    Never thought of the time gap between GMT and CET though. I always take a day of (864000000000) due to the difference from accountExpires and validto.

    I guess I would have to add or subtract another milliseconds value to match up the different time zones we have (plants all around the world) if sdomeone actually would complain about a user being locked too early just because of the day hasn't passed yet. I guess the local Domain Controllers in every country handle the date correctly.

    If ever needed I would use a time zone difference in hours and store it on each company. Then I'd use this one in the script to add / subtract the amount of hours before calculating the new Date thingy.

    Best regards

    • Hi Dominik,

      Can you please let me know how to convert the current date to LDAP/filetime, so that enddate can be passed to the AccountExpires attribute in AD

      if (" ") > -1){
      Par = Par.split(" ")[0];
     // Add T00:00:00 if needed
     if ("T") == -1 ){
      Par += "T00:00:00";
     var splitted   = Par.split("T");
     // 1st part
     var splittedDate  = splitted[0];
     splittedDate    = splittedDate.split("-");
     var year    = splittedDate[0];
     var month    = splittedDate[1] - 1; // Minus 1 needed
     var day    = splittedDate[2];
     // 2nd part
     var splittedTime = splitted[1];
     splittedTime   = splittedTime.split(":");
     var hours    = splittedTime[0];
     var minutes   = splittedTime[1];
     var seconds   = splittedTime[2];
     // New date object
     var adDate   = Date.UTC(year, month, day, hours, minutes, seconds);
     adDate    = adDate * 10000 + 116444736000000000 + 864000000000; // Has to be this high!
     // Error handling
     if (adDate == "" || adDate == null || adDate.toString() == "NaN" || Par >= "9999-12-31"){
      adDate   = "9223372036854775807";
     return adDate;

    This should help. Parameter can be either formatted like "2018-04-25", "2018-04-25 12:15:00" or "2018-04-25T12:15:00" Please test if it fits your needs. Maybe the calculation of adDate has to be adapted, but it works for me
