some code i was playing with that seems like a good starting point.

<dtml-call "REQUEST.set('x', [ZopeTime(), ZopeTime(), ZopeTime()-8, 4,
5])">
<dtml-call "REQUEST.set('v', [7, 8, 9, 10])">
<dtml-call "REQUEST['x'].extend(v)">
<dtml-call "REQUEST['x'].sort()">
<dtml-var x>

x gets rendered
[4, 5, 7, 8, 9, 10, DateTime('2000/04/19 01:15:42.8905 US/Eastern'),
DateTime('2000/04/27
01:15:42.8898 US/Eastern'), DateTime('2000/04/27 01:15:42.8902
US/Eastern')] 

hope this helps
