So what you really need is a filter operator that can do the conversion and
be used inside a sortsub operator. @Eric ?
If you're willing to use an "update" button, one solution would be a button
that creates "published-tw" (date in TW format) fields for any tiddler that
has a "published" field. Then you could have the TOC sort on the
published-tw field. You would have to remember to periodically perform the
"update" whenever you had data changes. This two-step approach makes
certain activities in TW much easier to handle.
So the code to update the field might look like:
<$button>Update Publication Dates
<$list filter="[has[published]]">
<$wikify text="""<$macrocall $name=convertdate from={{!!published}}
to="[UTC]YYYY0MM0DD0hh0mm0ss0XXX" />""" name=result >
<$action-setfield $field=published-tw $value=<<result>> />
</$wikify>
</$list>
</$button>
Be sure to make a backup before trying this of course. Also, this assumes
that you have the latest version of Eric's converdate macro installed.
