maybe this:

var str = $('#time').text();    var t = str.match(/[\d:]+(?= pm)/g);  (var = 0; < t.length; i++) {    var match = t[i].split(':');    var th = +match[0] + 12 + ' h';    var tm = ' ' + match[1];    var ft = th + tm;    var str = str.replace(t[i], ft).replace(/pm/g, '');    $('#time').html(str);    }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div id = "time">12:00 test text @ 9:10 pm se second 6:00 pm doe not works.</div>

the regex matches numbers (\d) , colon if followed pm (leading space). each match split on : , 12 added first split (to make 24hr clock).
