So, it looks like you're looking for something a little more advanced than a standard sort.

// WARNING: THIS IS *NOT* BY REFERENCE. IT RETURNS A NEW ARRAY.
function getSortedTimes(array $group)
{
    $tmp = array();
    foreach( $group as $times )
    {
        // Basically, I am pairing the string for the start time with 
        // a numeric value.
        $tmp[$times] = strtotime(substr($times, 0, strpos($times, '-')));
    }
    // asort is like sort, but it keeps the pairings just created.
    asort($tmp);
    // the keys of $tmp now refer to your original times.
    return array_keys($tmp);
}
