According to bitsler this is their dice game's rng method. I don't see anything relating to the time, so that answers my question.
'luckyNumber' is the roll, and is between [0 - 99.999]. This version seems to be PHP.
$seed = $serverSeed.'-'.$clientSeed.'-'.$nonce;
do {
$seed = sha1($seed);
$lucky = hexdec(substr($seed,0,8));
} while ($lucky > 4294960000);
$luckyNumber = ($lucky % 10000) / 100;
if ($luckyNumber < 0)
$luckyNumber = -$luckyNumber;
echo $luckyNumber;
