Help re. checking for password expiration/time comparisons

Hi,

I need to check whether a user's password in Active Directory is expired. I've used Sun's LDAP JDK to retrieve:

maxPwdAge = how long the passwords in AD are valid
lpwdLastSet = when the password was last reset

I have the following code so far:

GregorianCalendar Win32Epoch = new GregorianCalendar(1601,Calendar.JANUARY,1);
Date Win32EpochDate = Win32Epoch.getTime();
GregorianCalendar Today = new GregorianCalendar();
Date TodaysDate = Today.getTime();
long TimeSinceWin32Epoch = 10000 * (TodaysDate.getTime() - Win32EpochDate.getTime());

if ((TimeSinceWin32Epoch - lPwdLastSet) >= maxPwdAge)
{
System.out.println("********* EXPIRED **************");
}
else
{
System.out.println("********* NOT EXPIRED **************");
}

But, with the above code, the TimeSinceWin32Epoch value always seems to be less than 'lPwdLastSet'.

For example, I just did a test where I first reset the password in AD. Then, I ran my test program and got:

lPwdLastSet = 128014798644537904
TimeSinceWin32Epoch = 128014619454130000
maxPwdAge = -37108517437440

Can anyone tell me what I'm doing wrong?

Thanks,
Jim
