When using the TrackingStats Special page the begin and end arguments are not fully respected as we transform them to

$end_format = 'Ymd235959';

$range[0] = strtotime( date( 'Ymd000000' , wfTimestamp(TS_UNIX, $timestamp) ) );
$range[1] = strtotime( date( $end_format , wfTimestamp(TS_UNIX, $timestamp) ) );

no matter what they are set to. Thus a custom time at 00:00:00 and 23:59:59 works correctly but all others will get overridden.
