php-fpm decorate_workers_output = no removes timestamp

Description

The following code:

<?php
error_log('testing...');

• Note: all output is to the error_log file

Resulted in this output:

[22-Feb-2023 21:06:21] WARNING: [pool www] child 21211 said into stderr: "NOTICE: PHP message: testing..."

So in my www.conf file, I set this:

decorate_workers_output = no

Which resulted in this output:

NOTICE: PHP message: testing...

But I expected this output instead:

[22-Feb-2023 21:06:21] NOTICE: PHP message: testing...

Is there a way to keep the timestamp, but remove the rest of the worker decoration?
