From Plone 5.2.4 Error: unknown type name: 'clock-server'

It seems that Zope won't start anymore if we try to use the <clock-server> directive in zope.conf

console reports

Error: unknown type name: 'clock-server'
(line 46 in file:///home/sauzher/buildouts/current5/parts/instance/etc/zope.conf)
For help, use /home/sauzher/buildouts/current5/bin/instance -h

zope.conf:

[...]
python-check-interval 1000
<clock-server>
    method /Plone/@@tick_hourly
    period 3600
    user zopeuser
    password 123123
    host localhost
</clock-server>
[...]

without looking at the implementation this add-on probably is relying on ZServer asynchronous server.

On the move to Python 3, the ZServer got bumped.

There is hope though, @datakurre has been working on using Twisted and have plone site on top of it. Then we could spin again an asynchronous server that could handle timed events, like this add-on expects 🎉

If all the above does not make sense, sorry! 😅

Something like this, my serve as a basis: https://github.com/collective/collective.taskqueue/blob/twisted/zope.tac

Thanks @gforcada! I was not aware of Zserver funcionality loss.
I think I'll rely on classic cron then.
