I don't understand how to use <uptodate> for this purpose.
My reading of <uptodate> is that it will set a property if a file is
up-to-date with respect to another file (based on a merge mapper for my
case). I currently use <uptodate> for determining whether certain
operations need to be performed (setting a boolean property), but only
at a very coarse level. My requirement is to select (create a fileset
of) typically 10 to 50 files out of 4000 that have changed recently and
perform an operation with that fileset -- such as creating a zip archive
of all files that have changed since the last zip archive (my reference
file) was created. Other tasks are running file-specific tests on only
those files that have changed (those in the "newer" fileset).

You can use <uptodate> to select the newer files.
Or Ant-Contrib's <outofdate>, which I find more convenient, since
avoids having multiple targets, but it adds a dependency. --DD

I would like to do the equivalent of a "find -newer reference_file ... |

would like to archive only the files that have changed since the last
major archive into a smaller, faster, "delta" archive; much like an
incremental backup works.
The <date> selector in a <fileset> looks like the logical solution, but
it appears to only use a date-time string and not a reference file to
specify the date.
Is there a way to use the date-time of a reference file, instead of a
string, for the <date> selector?
Is there a way to set a property with the date-time of a reference file
so that the property can be passed to a <date> selector?
Is there another way to accomplish my goal, such as a way to use
<depend> with a single reference file?
