Php Date Condition不会为True

I am using this code for Condtion but I dont know why the condtion is going False

<tr
    <?php if ($LevelName['Status'] == 'Yes') { ?>
        style="background:#DCFEB7"
    <?php } ?>
    <?php elseif (strtotime(date('Y-m-d h:i')) > strtotime($LevelName['ReportTime'])) { ?>
        style="background:red"
    <?php } ?>
    <?php else { ?>
        style="background:orange"
    <?php } ?>
>

I don't know why the backgound color not going to Red

getting this result in condition:

(Todat Date)392291420 > (DB Date)1392336360
