If you're dealing with Active Directory and need to get values like 'lastlogon', 'pwdlastset' or similar, you'll notice that AD gives the values as Windows FILETIME timestamps. That means, the values are 100-nanosecond units passed since 1.1.1600 00:00:00.
To convert these to unix timestamps which PHP's date functions understand, one easy way would be the following :
function win_filetime_to_timestamp ($filetime) {
$win_secs = substr($filetime,0,strlen($filetime)-7); // divide by 10 000 000 to get seconds
$unix_timestamp = ($win_secs - 11644473600); // 1.1.1600 -> 1.1.1970 difference in seconds
return $unix_timestamp;
}
