Use a format that's support by both zend php and hphp

Summary:
hphp doesn't support "24:00". Use "23:59:59 instead. This is causing the stat page only shows the '1 week' stat.

in hphp

hphpd> =strtotime('1 week ago')
1340143086
hphpd> =strtotime('1 week ago 24:00')

hphpd> =strtotime('1 week ago 23:59:59')
1340175599

in zend php

jungejasonmbp15:tmp jungejason$ cat timeformat.php
<?php

echo strtotime('1 week ago 24:00');
echo "\n";
echo strtotime('1 week ago 23:59:59');
echo "\n"…
