Hi, I just needed the same thing... here another way. Deleting Zope Objects in DTML based on timestamp. I created this for housekeeping of a file repository,very similar the the File Library app in the Zope Examples. This dtml-method deletes items of type "File" that haven't been modified in 45 days. Notice the syntax in the line: <dtml-call expr="manage_delObjects([_['id'],])"> I Google'd it, apparently its handing manage_delObjects a list of one item, and that item is the item "id" from the current namespace. The trailing comma is for a list of one item. To test it, I commented the manage_delObjects line, and included the commented lines below, to test for the correct results. <dtml-with Files> <dtml-in expr="objectItems('File')" sort="bobobase_modification_time" reverse> <dtml-with sequence-item> <dtml-if expr="bobobase_modification_time()<=ZopeTime()-45"> <!-- DEL: <dtml-var absolute_url><br> --> <dtml-call expr="manage_delObjects([_['id'],])"> <dtml-else> <!-- KEEP: <dtml-var absolute_url><br> --> </dtml-if> </dtml-with> </dtml-in> </dtml-with> <dtml-call "RESPONSE.redirect('filelist_html')"> Good Luck, -Jonathan Cyr Ausum Studio wrote:
Look for the object DateTime in the help files of your Zope installation. They have a nice set of methods to compare time dates.
Anyways, they all return false or true, so in your case I would convert the time dates to integers, then perform a simple subtraction operation, and check if the most recent date is greater to ... seconds_in_a_day * 5.

I am almost done writing the script but I need to figure out how to compare two dates. For instance, I have this: <dtml-var ZopeTime fmt="%m/%d/%Y"> <dtml-var modification_date fmt="%m/%d/%Y">
*** Now I need to compare the two dates to see if the ZopeTime is greater by 5 days.
Any ideas on how to do that using dtml?
