[x3d-public] Turning on and off simultaneous animations individually

I have added default values in the ProtoDeclare for outputOnly fields,
reverting back to passing out startTime, stopTime and enabled.
Referring to this repository:
https://github.com/coderextreme/ci2had/
I primarily wish to get this working:
https://github.com/coderextreme/ci2had/blob/main/resources/CleanedYouClocks.x3d,
but first, I want to get ManyClocks.x3d working, because it precedes
CleanedYouClocks.x3d, but feel free to get it working first (it's a cleaned
up version).
If all else fails, I'll probably strip out the Proto (ugh!).
--------------------------------------------------------------
I have confirmed that this doesn't animate:
https://andreasplesch.github.io/Library/Viewer/index.html?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/ManyClocks.x3d
--------------------------------------------------------------
This does animate:
https://create3000.github.io/x_ite/playground/?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/ManyClocks.x3d
---------------------------------------------------------------
Castle Model Converter produces errors. The viewer doesn't animate,
probably because I use HAnimDisplacers. There are no scripts, in an attempt
to appease people who don't like scripts. We now have a good example that
has HAnimDisplacers, but no scripts.
$
~/Downloads/castle-model-viewer-5.3.0-win64-x86_64/castle-model-viewer/castle-model-converter.exe
--validate resources/ManyClocks.x3d 2>&1 |sort -u

FreeWRL kills JavaScript for some reason (there's no Script), but still
doesn;'t animate (try pressing Fear).

Schematron reports a bunch of problems, all of which I ignore. See

There are many info issues when validating with X3DJSAIL, but I'm not sure
about this one:
$ java -cp ~/Downloads/X3DJSAIL.4.0.full.jar
