Hi Tonico.

Thanks very much - worked first time!

My macro is:-

<div metal:define-macro="ukdatetime_or_null">
     <div tal:condition="RawDateTime">
         <span tal:replace="python: RawDateTime.strftime('%d/%m/%Y 
%H:%M')">Date</span>
     </div>
</div>

...and the useage is: -

<td tal:define="RawDateTime result/Created"
     bgcolor="#F5F5F5" align="left">
     <span metal:use-macro="here/formats_pt/macros/ukdatetime_or_null"/> 
         </td>

So the output is  "28/10/2004 14:15"

Fab - I was trying too hard!

I have a large number of places where I need to see if the SQL Server 
timestamp field is present in "result" - and only try to format it if it 
exists. /Just/ enough of a PITA (given the number of places I must do 
this) to factor out into a macro!
