u have answered u're own question here;

as an alternate u could iterate through a fileset (use ant-contrib <for> task,
which can take a <fileset>, that iterates through each file) testing a
condition each time (http://ant.apache.org/manual/CoreTasks/condition.html),
that is setting a property if file X datestamp is newer then file A....once
again u could use ant-contrib <if> to achieve this.
another way to build up a fileset is to manipulate in another language, for
example you could have a bit of javascript that does this checking, which
builds up a fileset.
gl and post your solution back for the list, Jim Fuller
